Radar thread - specs & discussions

Postby Singha » 17 Feb 2005 12:43

Please use this thread to post technical specs of modern radars ranging from
small ones to the biggest and questions / discussions.

I am esp interested at the moment in comparing the physical and technical
characteristics of Thales RBE2, RDY2, RC400, Zhuk for the Mig29, Grifo S7,
Chinese radar for J-10 (KLJ8?) and ofcourse MMR. stuff like antenna diameter, weight, modes, mtbf, ranges, Tx power....

Info is very thin in public websites...perhaps some among u have access to
Janes and other resources :P ?

Harry posted on keypublishing that diameter of MMR is around 650mm compared to 624mm for the Zhuk-ME. Hope he can shed some more information regarding this, i am not radar expert myself.

It means either 1) that all that speculative nonsense on the small size of the LCA's nose is false or 2) the radar can potentially outrange the Zhuk-ME, given that the power o/p is also higher. The third parameter to consider is the DSP, of which we have no info. Advertised Zhuk-ME range is 120 km against a 5 sq.m target but the Phazotron-NIIR director general (source: Airfleet) also claims 120 km against a MiG-21 of 3 sq.m RCS.

It's also true that Phaz delivered Kopyos with an MTBF of 11 hrs to the IAF. The IAF forced them to spend more until they got it upto 110 hrs, still not quite up to the advertised 150 hrs.

WTF? 11 hrs? Are the Russians on crack when they design and build their stuff? I was looking more and more favorably at the Mig-29M2 for the IAF's MRCA but this bit of news about the Kopyo brought me back to reality about the nature of Russian eqpt... glossy brochures, political arm-twising, and heavy lobbying by retired officers, nothing more.

it will be a horrible decision to go for the Mig29 as a strike fighter and be
the test horse for this concept. One can be sure of umpteen integration issues with our weapons and avionics.
we should ofcourse upg the existing IAF Mig29 with the Mig29K cockpit and
Bars29 radar. Let them remain A2A birds with some new capab like firing the
KH series of missiles.

umm, err, umm . . . Dunno guys, dunno.

This is *not* the type of thread that is good to have on the forum. Yes, I know the arguments about the goras knowing everything and only the janta being kept in the dark, but still . . .

It's upto the admins but I think you're skating on thin ice here - even if it's only kept to open source stuff, it's still dangerous collating this type of thing.

Sorry RS, JMO.

The MTBF issue is nothing secret. It was covered on royfc (or similar) long ago and even posted here, I think.

The stated claim for the LCA MMR puts it between the Kopyo M and the Zhuk M, with a range of 100 km, 10 targets TWS and 2 engaged simultaneously.
The real use of the radar is to gain familiarity with airborne FCR's, devise the appropriate algos for air to air and air to ground work and then improve upon what we have presently. The CAB AWACS program is seeing work done upon AESA as well and will require considerable work on sensor fusion- basically taking the Direction Finding data from the ESM/ ELINT kit, tying that in with the radar's feed and displaying it as one. The good thing is that we are using more COTS components, so we do have access to more computing hardware.

Re-post :


Force Magazine - April 2004


India is reviving the development of an indigenous Airborne Early Warning And Control System (AEWACS), which it had abandoned in 1999. “We have submitted a proposal to build an AEWACS with a next-generation active phased-array radar installed on a smaller aircraft, unlike the rotating antenna in the earlier Airborne Surveillance Platform (ASP),” said K.U. Limaye, director, Centre for Air Borne Systems (CABS). Limaye, who is also Director of the Electronics and Radar Development Establishment (LRDE) of the state-owned Defence Research & Development Organisation (DRDO), added that the airborne radar could be integrated on a Brazilian Embraer 145 aircraft.

The new AEWACS' mission avionics and sensors will be integrated via a dual MIL-STD 1533 B digital databus, with software programmes providing tactical aids, cues and alerts. The mission system will provide automatic radar control, automatic detection and track initiation, reduced false alarms, improved track continuity, sensor and databus fusion and modern communications management. It will also provide adaptive tracking performance, fast track update rate, reliable local situation display and computer-assisted decisions.

The LRDE-developed roof-mounted radar will be an active phased-array, pulse compression, Doppler radar operating in the S-band. The fixed antenna, with extremely low sidelobe levels, will comprise 200 transmitter/receiver modules mounted on top of the aircraft's fuselage. The best range performance will be achieved in a 150 degree sector sideways, with the performance reduced in forward and aft directions outside of this sector. The instrumented range will be 243nm and the typical detection range for a combat aircraft-sized contact will be 190nm. The radar's electronically scanning beam will be controlled by an automatic and intelligent energy management system which will optimise the beam position and compared to conventional, rotodome solutions, will provide quicker detection verification, increased tracking range, and improved tracking performance even for highly manoeuvring targets.

Work on the ASP's Technology Demonstrator (TD) began in earnest and the first flight of the TD, an Avro HS-748 twin-turboprop aircraft equipped with a rotodome fabricated by BAE Systems, took place in November 1991 at the ASTE's Bangalore facility. By 1994, the LRDE and state-owned Bharat Electronics Ltd (BEL) had completed development and fabrication of the ASP's radar and related electronics and a fresh round of technology evaluation and flight testing got underway, following a funding of Rs 250 million from the DRDO. By mid-1996, work on most aspects of the ASWAC project had been completed, and the LRDE radar demonstrated an effective range of 300km when called upon to detect a low-flying target cruising at Mach 1.5 speed. However, the sole ASP TD perished in a fatal crash at Arrakonam near Chennai in January 1999, killing eight personnel, and the ASWAC project was consequently put on hold.





India's Big AWACS Plans; Mini-concept provides another chance to use research begun in 1999

AWST - April 2004


Within two months of signing the $1.1-billion Phalcon Airborne Early Warning and Control Systems contract, India is looking to revive its own $400-million AWACS project.

To be called the Mini-AWACS system, the project harkens back to the indigenous airborne surveillance platform (ASP) effort shelved by India's Defense Research and Development Organization (DRDO) in 1999 after a modified Avro HS-748 crashed, killing four scientists and four air force officers on board. The accident was blamed on a rotodome that blew off, indicating a failure in the modification process.

However, this time DRDO is expected to mount the Mini-AWACS' phased-array radar on an in-production executive jet, according to K.U. Limaye, director of the Electronics and Radar Development Establishment and head of CABS. An experimental radar is already in testing, he added.

India has begun talks with Israel about joint production of the Mini-AWACS, according to DRDO chief V.K. Atre. After Russia, Israel is India's second-largest weapons system supplier and the two countries are looking into jointly funding reasearch and development in electronic warfare systems, as well as in major undertakings to build Searcher II and Heron unmanned aerial vehicles.

The construction of AESA radar in Russia

Postby Igorr » 24 Feb 2005 12:48

Interfaks, 15.02.05
The corporation "Phazotron -NIIR" started the production of the basic elements of radar AESA.
Corporation "Phazotron -NIIR" completes the construction of airborne radar (BRLS) with the active impulse phased antenna cascade (AESA), reported general director - design project leader of corporation Anatoliy kanashchenkov. "The construction of radar with the impulse phased antenna cascade of the next generation will be completed in the first quarter. The antenna with a diameter of 700 mm already went into the production ", it reported A.Kanashchenkov. "Phazotron -NIIR" actively works at creation by promising BRLS AESA for the new light export- oriented strike aircraft, created on RSK "MiG", said the head of corporation. According to him, in the production of the radiating elements AESA "were outlined very positive changes". "The quadrupled module is prepared now. Naturally, as with any experimental design work, there are complexities - some elements thus far have run-away characteristics. But this problem is decided ", it said A.Kanashchenkov. According to him, the corporation proceeds with additional financial expenditures on this theme. A.Kanashchenkov it reported that the elements of radar AESA are created in the cooperation with several enterprises. "Now the technology is mastered - three firms, which participate in the project, organized the joint production, which is modernized, in order on its base to form the rule of the creation of modules", said A.Kanashchenkov. According to him, the production is created on the base of Tomsk institute "MIKRAN", with which there is a sufficiently large production, which makes the advanced means of communication. According to the data Of a.Kanashchenkov, one firm, begun to operate in the cooperation, specializes in the region of semiconductor technology, and another has a technology of the production of monolithic elements in the composition of the receiving-transmitting module. "" Phazotron -NIIR Corporation "determines the ideology of the leading and promising works", it said A.Kanashchenkov

er, I doubt we will manage such a huge AESA for AEW considering we onlee were toying around with a 64 cell toy kit in AI03.

methinks it will be a PESA and later on upg to AESA when we master the
tech via a smaller project like MMR-upg. As of now I dont think we have the
tech to manufacture the modules in volume and cheaply, france had been asked but they arent the greatest at that game themselves and will demand a huge pound of flesh like price padded scorpenes.

what kind of system is the Ereyie ?

ok I recall now..werent there two types of aesa and this Ereyie had the
lesser for while the APG-77+ the newer format ?

The Ericsson PS-890 Erieye radar uses an active array with 200 solid state modules. The range of the S-band, 3 GHz, side looking radar is 300 km

Erm Singhaji,

That 64 cell design is meant to be a module of a larger radar. Not standalone, iow it can be scaled up. The Erieye has only 200 modules as you note. Now consider what DRDO/BEL are doing. Yes, we are seeking codevelopment of tech to move faster, but this is one area where we can go it alone too- if others show us some attitude. The CABS design is AESA from the word go. PESA is not planned.

Guys... if you click on the RC 400 pdf from the link mentioned above... it shows a picture of the LCA as a potential user of the RC 400 radar...
if i am not mistaken this is being offered to the fc-17 also... also it does not seem to be any effective as the RDY-2... can any one plz tell me that the MMR is a better radar than the ones offered... I will have sleepless nights otherwise...

Yuri Belyy (NIIP Tikhomirov): "from" the Bars "- to the radar of the fifth generation
"Nezavisimoye military review '. October of the 2002

- apropos of the radar of new fighter (PAK FA) goes the controversy, such as it must be: on the base WITH AESA or as alternative - certain simplified intermediate version, and radar WITH AESA to place already later - on the modernized machines. What you do think in regard to this?

- earlier we spoke in favor of the specific staging character of this development. And they proposed during the first stage to make radar with PESA. Until today it is actually accessible and there is the readiness of developer and producers to make this work in short periods. But, from other side, is a specific logic in the fact that if we begin to make intermediate stage, then development can be longer and leave in the established periods. This will lead to the dispersion of forces and facilities. As a result we solved, that it is necessary to make immediately final version - radar WITH AESA. Especially as we already today have locators with PESA.
For example, contemporary radar "Bars" for the fighter Su-30MKI. There are prospects for the growth of its distance and other functional characteristics. We were included in this competition and we will propose AF our solution by the locator WITH AESA. All the more, as 4 already earlier he spoke, we won competition in the Defense Ministry RF to the conducting by complex NIR on the creation of AESA technology for interspecies designation. This very well is entered over our long term, in our today's work. There is understanding the essence of problem, there is cooperation, is already carry out consideration particular tech charachteristics of AESA for different purposes. On the whole, we consider that NIIP is ready to solve this task.

- And how now the state of works on the radar "Bars"? recently the Communication passed, that the delivery of first party Su-30MKI to India was completed.

- on the contract are placed three stages of the version of deliveries RADAR. Final stage - so-called Mk3 - use as the controlling radar machines BTSVM - HIGH SPEED DIGITAL COMPUTER of Indian production. now We passed the first stage - in our computers with the limited volume of tasks. Positive conclusion was obtained during April, and from June already here send deliveries. And when some speak: "Bars" can carry out only the limited volume of tasks - this is very incorrect assertion. Nothing similar! we have confirmed the given volume of tasks within the framework of contract. In reality not only the version "Bars" Of mk2 is ready to tests, but also the version Of mk3. In those works, which were carry out on checking of the version Of mk1, they were obtained results on the confirmation of further versions. this fact we Simply do not advertise separately.

- if we compare "Bars" with the foreign analogs, as it does appear against the western RADAR?

- to compare indeed not with which. There are no analogs abroad thus far (2002). Only, with which it is possible it to compare - with the "rafal radar ". This is only fighter with the analogous locator, which today flies. Antenna with the electronic scanning of ray is there also established. However, information on "rafal" is very small. If we take purely quality indicators, then Frenchmen realized all key regimes "air-to-air" - these are multipurpose tracking, multipurpose firing, and also work over the surface. But, for example, on the multipurpose firing we do not have generally information on "rafal". But how to compare?
Well and all the remaining existing today aviation radars - with the slot arrays (SHCHAR). But SHCHAR have limitations: their potential, at other conditions being equal, is less. there are limitations also on the firing - there it is possible to attack purposes only in the very narrow zone. In comparison with them, the method of electronic scanning has many advantages. If we analyze the materials, which appear on the European and the American about AESA, then everything is reduced to the comparison of the characteristics of radars with SHCHAR and electronic scanning. Information about the fact that the precisely active elements accomplish electronic scanning, practically does not sound. And we also always said that the matter not in the method of the formation of the antenna radiation pattern, but in the quite electronic scanning, which gives essential tactical advantages.

on the lines of MESA?

--

The MESA antenna is an innovative aperture that provides a 360-degree azimuth scan with no mechanical rotation. Attached to the top aft section of the fuselage, it consists of an advanced composite structure that supports side-emitting electronic manifold arrays and a "top hat" end-fire array. Its ultralight foam composite sandwich construction enables state-of-the-art performance at a fraction of current system weights, thereby allowing additional time on station for the aircraft.

MESA will provide multiple surveillance applications, using pulse doppler radar forms for air search and pulse forms for maritime surface search. It also will provide in the same aperture an integrated civil and military identification friend-or-foe (IFF) capability.
http://www.irconnect.com/noc/press/page ... ml?d=33593

http://www.globalsecurity.org/military/ ... /e-737.htm

A Multi-role Electronically Scanned Array (MESA) radar is the critical sensor aboard the 737 AEW&C. The MESA radar is the latest generation airborne surveillance radar system for mid-cost AEW&C. The electronically scanned array features three apertures sharing "L" band frequency transmit and receive modules to attain 360 degrees of coverage. The "L" band frequency is an optimum blend of range, detection capability, size and weight. The steerable beam, L-band electronically scanned array is designed to provide optimal performance in range, tracking, accuracy and growth. The radar is able to track air and sea targets simultaneously and can help the operator maintain control of high-performance aircraft while continuously scanning the operational area. The 'top hat' provides a practical solution for fore and aft coverage while maintaining the low drag profile of the dorsal array system. This allows the system to be installed on the mid-size 737-700 platform without significant impact on aircraft performance.

Phased array variant of the Zhuk MS. Would have to be downsized to fit into the MiG29 K. Uses a new phased array antenna developed by Phazatron, which that firm claims to be cheaper to manufacture than the Bars antenna.

Initial targets for the full scale MF, were greater range than the Bars, more than 20 targets in TWS and 6-8 engagements. But Phaza, has a rep of BS'ing and shooting their mouth off before development is complete (case in point check their ME specs- went from a confident 20 targets in TWS mode and 4 engaged, to 10 and 4 respectively). So it is pretty unlikely that any of the TWS> 20 and engagemen~6-8 were met. The Zhuk MF was tested on the Su33UB testbed and was still in flight trials. The radar has also been informally called the Sokol. I would expect it to be around approx the 10 target TWS and 4 target engagement benchmark set by the ME. Furthermore, the Russians themselves have been more interested in the Bars; its regarded as more mature and to Phazas discomfort, its NIIP which has hogged the spotlight and the funds, with hefty exports of its NOO1 series to China.

And for the 29 version- Phazatron has proposed such a variant and calls it the Zhuk MFE. it is currently claimed to be in laboratory tests. Flight tests yet to be conducted. The range , TWS performance, engagement would have to be greater than or equal to the slotted array ME for the IN to select it- apart from the interleaving modes advantage of the PESA system.

Also apart from range, TWS+ engagement, modes and ECM performance, I dont see any reason why a MF would be chosen over a Bars-29, unless the MF was able to provide greater scanning limits than those currently enjoyed by the Bars (+/- 70 and +/- 40 deg.). For naval ops, thats an advantage which the slotted array ME provides over AESA/ PESA radars. It can provide scan angles of +/- 85 deg azimuth/+56 and -40 deg in elevation.

Lecture by Dr A I Kanashchenkov ( Director General of NIIR Phazotron )

On the Zhuk-MFE


Phazotron has developed the ZHUK-MFE radar, which has phased array antenna free from the above said drawbacks. It was possible to achieve, using new principles of PAR design and UHF technological solutions. ZHUK-MFE weight and tactical characteristics are close to ZHUK-ME characteristics. It allows installing this radar onboard upgraded MiG-29 aircraft without changing its design. Now ZHUK-MFE radar undergoes laboratory tests. At Customer’s request Phazotron is ready to place this radar on MiG-29 or other type of aircraft and begin its series production.




On the Kopyos for -21-93


In India Kopyo-21I radar is well known. It is installed on MiG-21 Bis UPG aircraft. Kopyo-21I is the first radar in a number of unified radars: Kopyo-M, Kopyo-25 and Kopyo-A, designed on a new element basis.
Phazotron has developed Kopyo-25, a podded version of Kopyo-21I. It has undergone flight tests on Su-39 aircraft. The container version of the radar allows to equip the aircraft, which was not equipped with the radar earlier, with an advanced radar without essential adaptations of an aircraft. It expands tactical capabilities of an air complex. Kopyo-25 may be offered for HAL produced MiG-27L upgrade.

Kopyo-М is similar to Kopyo-21I, however due to transition to a new element base and new signal processor, it has 25 % increase in range of air target detection, Time of a radar map generation in synthesized aperture mapping mode has become twice as less. The radar is much more reliable, has smaller weight and overall dimensions. Its characteristics allow considering Kopyo-М as the radar for further modernization of MiG-21 Bis aircraft or similar class of aircraft. It is expedient to consider jointly with the Indian experts the feasibility of fitting this radar on IAF light aircraft like LCA. At present Kopyo-М undergoes flight test.

EADS makes active radar a top business priority

Flight International 24-Feb-2004


EADS Defence Electronics predicts a significant growth in business over the coming years for its radar transmit/receive (T/R) modules, to reflect the increasing military interest in shifting from the use of mechanical arrays to more capable active electronically scanned systems.

The company has identified the business area as a top priority for the next five years, and has already made a heavy investment in supporting manufacturing techniques using gallium arsenide.

Each T/R module is roughly 7cm (2.8in) long, 1cm wide and 0.5cm deep, and has a power output of about 10W. Future arrays will be scaled according to the size and requirements of the host platform, totalling from several hundred modules to around 10,000 for ground-based air defence applications, says EADS.

Planned uses for the company's T/Rmodules include their integration with the Captor multi-mode radar now under development for the Tranche 3 standard of the Eurofighter Typhoon, NATO's planned Alliance Ground Surveillance battlefield-reconnaissance system, and the TerraSAR-X radar mapping satellite, to be launched for the German research organisation DLR and Astrium next year.

Boeing Debuts Super Hornet with Advanced Radar System


(Source: Boeing Co.; issued Apr. 21, 2005)

ST. LOUIS --- Boeing will debut the F/A-18E/F Block II Super Hornet equipped with the revolutionary APG-79 Active Electronically Scanned Array (AESA) radar system at a ceremony at Boeing's St. Louis facilities today.

Featuring a fixed array with an agile beam that scans near the speed of light, the AESA will, for the first time, enable aircrews to conduct simultaneous air-to-air and air-to-surface operations with independent dual-cockpit operation. In air-to-air mode, the radar allows targets to be engaged at very long ranges, permitting weapons launch at maximum range and enhancing warfighter survivability and lethality. The system also offers high-resolution ground mapping at long standoff ranges for air-to-surface tracking.

The aircraft will be used as part of the AESA radar flight test program prior to entering Operational Evaluation (OPEVAL) in 2006.

Harry,

any specs for the Bars29??

BTW, how come the Kopoyo with 11hrs MTBO came in??... wasn't there any quality checks in the first place and whats the case with all the upgraded MiG-21s??


Also hope to see someone post the MTBO of other rarars ....

In the F/A-18 E/F, the front seater can monitor for A2A threats and engage them, while the back seater take care of A2G...all the advantages of an AESA/PESA...mode interleaving..

Phazotron's excuse was that mandatory Soviet-era quality checks and inspections of PCBs and processors was no longer the practice. The MTBF (Failure, not Overhaul) was increased to 110 hrs, still less than the advertised 150 hrs.

All western radars have much higher (advertised) MTBFs.

I browse from a university network, and have access to various military magazines so any service to BR forum and community will be a pleasure.

I was looking through Janes Radar And Electronic Warfare 04-05, and thought of some issues that could be of interest to BR folks.

----> No info on Israel's AESA 2052 which is now under testing as reported by Flight International in Feb. Hopefully janes will update itself in the next edition which should be in my lib by mid july "latest".

----> Not any good info on Bars N-011M. I have been following Jane's RAEW report on Bars continously for sometime and they seem to be happily ignorant of the fact that there are different versions of Bar being developed. According to them in their 04-05 edition max range for bars is quoted to be 140 kms. Paul aka overscan's page on russian avionics had 140 kms as range listed for very initial model of bars which was over the passage of time thoroughly upgraded for IAF. Jane's seems to be stuck in history.

On a side note for Phazotron-NIIR's Zhuk MF's radar it is said that it can track a 3 Sq m RCS target in forward hemisphere at a distance of 180 kms and in the rear hemisphere at a distance of 80 kms.

It is also said that it tracks 30 while engages 6 simultaneously.

Our BARS will track 15 or 20 and engage 8 simultaneously in the 3rd model which has Indian radar DSPs ?

Operating modes of Zhuk MF

Air to Air
Look up/look down, range while search, velocity search; 24 targest track while scan with simultaneous engagement upto 6 targets; single target track; raid cluster resolution and automatic terrain avoidance.

Close Air Combat
Vertical scan; head up display serach; boresight and wide angle.

Air to surface
Enhanced beam mapping; Doppler beam sharpening; synthetic aperture; enlargement; freeze; four target TWS; precision velocity update; air to ground and air to sea ranging and ground moving target indication and tracking.

Harry,

MTBF for Zhuk MF is said to be greater than 150 hrs according to Janes, any idea about MTBF of BARS.

coming back to Zhuk MF,

Freq: 8 - 12.5 Ghz
Power Output: 2 kW [average] ; 8 kW[peak]
Angular coverage: +/- 70 degrees in azimuth and elevation.
Cooling: air and liquid
Weight: 250-270 kgs class
Volume: 600 dm^3

According to russian sources, Zhuk MF is multiple pulse repetition freq[ low, med and high] MMR that comprises:

a low sidelobe, 1 m diameter phased array antenna
a liquid cooled, travelling wace tube transmitter
a software controlled, 'high stability' exciter
a multichannel reciver
a programmable signal processor
a high order language data processor

the antenna makes use of of non equidistant field distribution rather than tha traditional linear approach.

Something interesting about thales RDY radar that isn't mentioned in thales website but is mentioned by Janes RAEW 04-05 is,

"For future upgrading, RDY is understood to be potentially compatible with an electronically scanning array."

So basically RDY can be upgraded with active array if required. Something IAF should look into while buying M2K-5 MK2.

Also janes says that " thales also notes that it is able to offer an RDY synthetic aperture reconnaissance capability if required. and RDY can locate targets in high seas at ranges up to 296 kms."

In next post i will cover AN/APG68(V) radar equipping F-16 C/D models.

What is mean by MTBF of 150 hrs. What kind of failure is that. Does it "fail" for every 150 hours.
