Mumbai to get Doppler Radar by May 31

MUMBAI: The Doppler Weather Radar, which is much awaited since the July 26, 2005 deluge, will now be available to the city by May 31, a top official of the India Meteorology Department (IMD) here said.

"IMD Mumbai has procured an indigenous Doppler Weather Radar (DWR) from Bangalore based Bharat Electronics Ltd and we expect that installation will be completed by May 31, just before the monsoon begins," Dr R V Sharma, Deputy Director General of Meteorology told PTI on Tuesday.

The DWR will help the department in 'nowcasting' (predicting weather for next two to three hours) as it has several features that can be estimated like rainfall intensity, cloud droplet size, wind profile, Sharma said.

Part of the consignment has already reached Colaba Met office yesterday and the remaining are expected shortly.

"Since the site with connectivity facilities is available at Navy Nagar for installing DWR and the engineers from BEL are on their way, there should not be any delay in setting it up," Sharma said.

Last year, IMD had imported a Chinese made DWR but was denied permission by Naval authorities to install. Following this the DWR was sent to Delhi, Sharma said.

According to him, the existing cyclone warning system can only give features like clouds and their position.

On July 26, 2005, the city recorded 944 mm within 24 hours following which it was under water for almost two days, killing many people as well as livestock as there was no prior warning about the intensity of the rainfall.

IAF's radars 'inadequate, obsolete': MPs' panel

In a damning indictment, a parliamentary panel said on Thursday the surveillance radars of the Indian Air Force (IAF) were not only inadequate but were also obsolete and prone to frequent breakdowns.

Mod 2009-10 reports talks about:

Medium Power Radar (MPR) & Low Level
Transportable Radars (LLTR) : DRDO has
started design & development of these
4D (range; direction; height & doppler
velocity) Radars required by the IAF for
Air Surveillance. These Radars will use
many state of the art technologies including
advanced Active Array technology & Digital
Beam Forming. Initially 8 indigenous MPRs
and 18 numbers of LLTRs will be inducted by
the Indian Air Force.

Does it mean that our ground based AESA is in advanced stage of implementation. Reference to 8+18 radars mean that around 26 radars have been ordered? This seems to something like Rs. 2000-5000 crore order? This seems to be apart from orders of CAR around Rs. 2000 crore, WLR around Rs. 1000 crore and LRTR around Rs. 7000 crore, and off course indigenous AEW Rs. 2000 crore.

Mumbai to have Doppler Radar by month-end

MUMBAI: The city would finally have a Doppler Radar installed by the month-end at Navy Nagar in Colaba, a development which was much awaited since the July 26, 2005 deluge.

"The radar would be installed and functional by the end of this month," relief and rehabilitation minister, Narayan Rane told reporters on Wednesday after reviewing monsoon preparedness in the state.

Earlier, a similar radar, ordered from China was cancelled by the State Government citing quality norms. The radar to be installed now is of Indian make, Rane said.

The Government has initiated a mobile alert service to alert local people about emergency situation. Even the website of the Indian Meteorological Department would be updated on an hourly basis, Rane said.

IAI/ELTA Awarded a $57 million Contract to Supply its EL/M-2083 Radar

ELTA Systems Ltd., a group and subsidiary of Israel Aerospace Industries Ltd. (IAI/ELTA) has been awarded a $57 million (USD) contract from a foreign customer to supply its Long Range Air Defense Radar EL/M-2083. The radar is installed on a tethered aerostat and enhances early warning capabilities.

Surface-based radars have limited line-of-sight to low flying airborne platforms, so in order to achieve longer detection range, the radar is installed at high altitude, using tethered aerostats or an aircraft.

IAI's Corp. VP and ELTA President Nisim Hadas said: "IAI/ELTA has proven experience in aerostat-based air defense radar, and we are pleased that the customer has chosen us for this program. This contract will allow us to demonstrate our capabilities and unique technologies, and we are confident our customer will benefit from our systems."

IAI/ELTA develops and manufactures a variety of air defense radars on a variety of platforms – ground, air, and sea.

Any guesses on who the customer IS???

saar ji in regards to your first queschun i believe we use the THD 1955 and the stu 68 tinsheild radars. The thd is of french origin whereas the tin shield is of soviet origin. The tin shield is or was IIRC part of the sa 10 system as well. The THD is huge and is a fixed site radar onlee whereas the tinshield can be moved around as it is towed IIRC. Also the THD has massive ranges compared to the Tinshield. There was talk of upgrading these radars but I cant remember anything coming through onlee.

The rohini IMVHO will be sitting in a tier lower than the tinshield with the upper end being formed up by the LRTR and MPR onlee. I would imagine that from the rohini it will then come down to battery level rajendra's onlee. Also with the new barak II coming online I would hazard a guess that the radar systems for the Barak II will be getting wired up to the LRTR and MPR and then will be distributing data to Barak II's own Aesa radar. Overall I think the whole ADGES picture is going to change very very significantly. JMT onlee

India to get two more AWACS, other radars to make airspace impregnable
http://timesofindia.indiatimes.com/Indi ... 184271.cms

India will go in for two more AWACS (airborne warning and control systems), the "formidable eyes in the sky", after the last of the three Israeli Phalcons already ordered is inducted in December.

IAF is also on course to induct a wide array of radars, from 19 LLTRs (low-level transportable radars) and four MPRs (medium-power radars) to four Aerostat and 30 indigenous medium-range Rohini systems, towards making Indian airspace as impregnable as possible.

All this is in tune with the crucial plan underway to set up five nodes of IACCS (integrated air command and control system) across the country, with the first one coming up in the western sector facing Pakistan, to plug existing gaps in the country's air defence coverage.

Seamless data transfer from civilian and military radars as well as AWACS, all networked under IACCS, will make it possible to get the "air situation picture" at a central place in realtime. This will ensure that swift counter-measures can be mounted to thwart aerial threats soon after they are detected.

"We have already moved the case for two more AWACS," IAF chief Air Chief Marshal P V Naik told TOI. These will be in addition to the three Phalcon AWACS already contracted under the $1.1 billion project finalised with Israel and Russia in March 2004.

The complex project, under which the Israeli 360-degree Phalcon early-warning radar and communication suites were mounted on Russian IL-76 heavy-lift military aircraft was hit by several technical delays.

Consequently, the first AWACS arrived in India only in May 2009 and the second in March 2010. The third is slated to be inducted by this year-end.

"Phalcon AWACS are tremendous force-multipliers. We are having an excellent experience with them. They will get their final operational clearance by October-November," said ACM Naik.

IAF's capabilities to detect and track troop build-ups or aircraft movements even deep inside enemy territory, much further than ground-based radars, have certainly registered a quantum jump with AWACS.

Apart from detection of incoming cruise missiles and aircraft from over 400-km away in all-weather conditions, AWACS are also used to direct air defence fighters during combat operations against enemy jets.

Moreover, IAF and Navy are also on course to induct nine more Aerostat radars after getting two Israeli EL/M-2083 radars in 2004-2005 for $145 million. Similarly, IAF is slated to begin inducting 19 LLTRs from October 2011 onwards, while deliveries of light-weight LLTRs will commence soon. Four MPRs are expected to be delivered by December 2011.

Incidentally, India is also pursuing a Rs 1,800 crore mini-AWACS project indigenously. Under this, the indigenous AEW&C systems developed by DRDO will be mounted on three Embraer-145 jets, being obtained from Brazil for $210 million.

Never had the privelage to see the THD or the Scatters (which I forgot to mention

Once at the EME in baroda there was a combined IAF and Army exhibition and they brough in the Tin Shield I am talking circa 98 moi like a faithfool rocked up straight away was in year 10 back then and after getting a nice little intro to the tin shield asked the IAF guy "why dont we just ramp up the power once we detect an incoming fighter and roast the pilot and electronics?"

Raytheon Working on Tiny AESA Radars

The new radars might be as much as 10 times lighter than some of the company’s current AESA radars, which are designed to ride in the noses of fighter jets, and potentially could be installed in the leading edge of a wing, a missile’s radome, a UAV’s body, and elsewhere. Raytheon’s APG-79 AESA, which is carried on U.S. Navy F/A-18E/F Super Hornets, has a 95-pound array and a total system weight of 650 pounds.

Link

The growing UAV market offers opportunities for AESA now because Raytheon looks to build conformal radar that weigh 2 to 5 pounds per square foot and are less than an inch thick. That will allow them to be installed in places current radar just can’t go and they could be placed in UAVs with a six-foot wingspan.

The radar system employed by the PAD/AAD weapons is referred to as Swordfish and is in actuality a modified Israeli EL/M-2080 Green Pine radar system
The Indian SAM Network by Sean O'Connorhttp://geimint.blogspot.com/2010/09/ind ... twork.html

Wikipedia says following (without any reference) about Swordfish LRTR, “it differs from the Israeli system as it employs Indian Transmit Receive modules, signal processing, computers and power supplies. It is also more powerful than the base Green Pine system and was developed to meet India's specific BMD needs.”

Following is the news extract from the web about the Swordfish “He said the DRDO had sought foreign collaboration only for bridging technological gaps and accelerating technology development. The long-range tracking radars (LRTR) used for detecting targets for the interceptor missiles are modified Israeli Green Pine radars. The interceptor missiles use an indigenized Russian radio frequency seeker and the fire control radar is French. The LRTR currently has a range of 600 km, which the DRDO plans to upgrade to 1,500 km by 2011.” http://www.domain-b.com/aero/mil_avi/mi ... _drdo.html

my question is:
1.Is Swordfish LRTR, "Green pine Modified" or "Green pine derived (copied and enhanced) Radar"?
2.If it is GP modified then does it mean to field more LRTR, DRDO will have to import the GP in equal number?
3.If it is GP modified then, how is DRDO going to achieve the technical challenge of upgrading the GP to range of 1500 km by themselves?
4. Wasn't a third GP was impoted in 2005?

I got this article about LRTR

DRDO To Partner With PVT Firms For Radar Projects

As India inches closer towards the development of the advanced long-range tracking radars (LRTRs), the local private and state-owned firms are gearing up to benefit from the outsourcing contracts worth millions of dollars that will come their way.

The state-owned Defence Research and Development Organization (DRDO) has indicated that it intends to outsource the majority of the work in developing six to seven LRTRs worth $1.2 billion. The latest range of radars being designed will be an upgraded version of the LRTR already developed by DRDO in collaboration with Israel. These LRTRs will detect small targets in the 600-800 kilometer range.

Indian private and public sector firms that have evinced interest in grabbing a chunk of business from the LRTR project include state-owned Bharat Electricals Limited (BEL) and Electricals Corporation of India Limited (ECIL) and private sector majors like Larsen & Toubro and Wipro. The outsourcing work for the LRTR will include manufacturing ancillary gear to the sophisticated software needed to run various programmes.
The Electronics and Radar Development Establishment (LRDE), part of DRDO, develops radar systems and other related technologies for the defence forces. The latest feather in the cap of LRDE is the Long-range Solid State Active Phase Array Radar (LSTAR) programme. The LSTAR programme is a part of India’s prestigious India’s Airborne Early Warning and Control System programme. The LSTAR project has been approved by the Centre for Military Airworthiness and Certification. It has been integrated and tested on ground-based systems and qualified for airborne applications. The LRDE has developed the X-band active electronically scanned array (AESA) technology. The AESA technology allows ships and aircraft to broadcast powerful radar signals while they themselves remain under stealth. The AESA radar could be fitted on the indigenous ‘Tejas’ Light Combat Aircraft (LCA) by 2014 under the LSTAR project.

Indian Defence is also focusing towards more Battlefield Management Systems (BMS) and integrating the Indian Army, Navy and Air Force. This includes the development of sensors, digitally enabled weapons, information grids which will enable the efficient functioning of the weapons and networking of data.

According to Indian Army officials, a fully digitized system has been integrated by the defence sector which is the artillery combat command and control system (ACCCS). The ‘Shakti’ ACCCS has been inducted and it is a network of military grade computers which provides decision support for all operational aspects of artillery functions from the corps down to the batteries. This ACCCS will be operational within an year at all levels of the artillery, officials added.

Other significant developments that will enhance the network-centric capabilities of the Indian defence includes the design and development of an UCAV (unmanned combat aerial vehicle) which will not only conduct surveillance, gather intelligence and transmit it but will also help detect the target and destroy identified objects.The UCAV can be controlled at various command control centres.

Currently, India has radars like the ‘Swordfish’ which has a range of 600 kilometres and the DRDO plans to upgrade the capacity of Swordfish to 1,500 km in a couple of years. The LRDE has also produced the Indra-1 and Indra -2 radars that work on the Doppler principle. Indra-1 has a 50 kilometre range and is integrated with the fire control radar. Indira-2, an improvement over Indira-1, was designed as per the needs of the IAF which wanted a radar that can identify dense-formation targets and can be used even at high altitudes. LRDE has also developed the ‘Bharani’, a portable, short-range, light-weight radar which provides 2D surveillance, mainly in mountainous terrain, against aerial targets. Besides that, LRDE’s portable Battle Field Surveillance Radar (BFSR) – Short Range has been developed and it is an all-weather automated detection of intrusions system was needed. Over 1,400 BFSRs are now being used by the Army against moving surface targets. A BFSR radar that offers foliage penetration is under development.

The LRDE has also developed an electronically scanned C-Band Doppler Weapon Locating Radar for use by the Artillery Corps called ‘Rohini’ which is a 3D, medium-range, vehicle-mounted surveillance radar that offers 360 degree coverage and has a range of 150-180 kilometre range. It is used against low, medium and high-flying targets. It is designed for the IAF and will also be part of the Akash missile system. LRDE has also developed ‘Aslesha’, a 3D low-level, light-weight radar designed for use in mountainous terrain and against aerial targets. There is also ‘Rajendra’ which is a multi-function, phased array radar and is the primary sensor at the battery level for the Akash weapon system. It can perform extensive searches, track multiple targets and missiles as well as command and guide multiple missiles concurrently.

IAF wants radars for hilly terrain
http://timesofindia.indiatimes.com/indi ... 610126.cms

NEW DELHI: IAF now wants a major induction of long-range surveillance radars (LRSRs) and high-power radars (HPRs) to bolster air defence coverage in ''hilly terrain'' in the hinterland as well as along the borders with China and Pakistan.

This comes after IAF has already inked contracts for 19 LLTRs (low-level transportable radars), four MPRs (medium-power radars) and 30 indigenous medium-range Rohini radars, among others.

Apart from lightweight mountain radars for high altitude areas, plans are also afoot to procure nine more Aerostat radars to add to the two EL/M-2083 Israeli Aerostats inducted earlier as well as two additional Awacs (airborne warning and control systems) to supplement the first three Israeli Phalcon Awacs bought under a $1.1-billion deal.

The overall aim of all this is to ensure Indian airspace, which still has several gaping holes, especially over central and peninsular India, becomes impregnable against hostile aircraft, drones and helicopters.

As for the LRSRs and HPRs, IAF's global request of information (RFI) says these active aperture phased array radars, which will ''be used for air defence surveillance, command and control in hilly terrain'', should be able to classify large, medium and small aircraft, drones and helicopters at a range of 450 to 600km automatically.

Though IAF is yet to specify numbers, the procurement is likely to be large since the RFI specifies that the project will involve a ''phased manufacturing programme'' leading to indigenous production under transfer of technology.
With advanced ''electronic counter-counter measures'', the LRSRs and HPRs should also be capable of being integrated into the IACCS (integrated air command and control system).

What is the difference between Tracking and Surveillance Radar?
Can the Swordfish be modified, (it already tracks 600-800kms)?

dinesha · Post by **dinesha** » 23 Sep 2010 08:14

What is the difference between Tracking and Surveillance Radar?

A surveillance radar is designed to continuously search for and detect new targets. The basic surveillance radar function has a 2-dimensional (2-D) plot showing the target object position in degrees from North (azimuth) and range (distance) from the radar. Radars that can determine azimuth, distance, and elevation are called 3-dimensional (3-D) radars. A tracking radar calculates a path for individual targets by using radar return echoes from one scan to the next, and are usually 3-D radars. Radars that perform both surveillance and tracking are loosely called multi-mode radars.

THD type fixed radars are very vulnerable these days to accurate BM or CM attacks - both of which the chi-paks possess in ample measure and getting better.
they might still have some role sited 1500km away on a hill in central india as a 'eye of sauron' thing but situated in delhi or nearer, they are quite vulnerable.
they might provide a efficient soln to monitor wide area in peacetime over peninsular and eastern india with minimal sites.

the future probably belongs to S1850M/Green Pine type PA radars mounted on truck trailers and capable of being deployed anywhere. they may not match
the THDs claimed 1000km range, but they can track 1000 targets while scanning and generate accurate data for SAM radars.

EW ASSETS

Fifty four EW sites have been identified in India. The primary assets are THD-1955, P-12/18 (SPOON REST), and 36D6 (TIN SHIELD) radars. Thirteen THD-1955 radars arrayed primarily along the border region from Pakistan to Myanmar provide a significant amount of EW coverage. EW coverage is enhanced by fourteen 36D6 radar sites, arrayed primarily along the border with Pakistan. The 36D6 is significant as it can provide both target track data to SAM batteries as well as GCI support for Russian-origin fighter aircraft such as the MiG-29 (FULCRUM) or Su-30MKI (FLANKER-H). ...

When you combine all these news reports/analysis, here is my guess as to what the total orders might look like for the LRTR:

7 - LRTR based on Swordfish (600Km+) to cover the gaping holes over the "central and peninsular India"
13 - LRTR based on Swordfish (600Km+) that will replace the aging THD-1955 radars

Plus, replacement for an unspecified number of the 200km+ P-12/18 radars and augment the 14 160km+ 36D6 radars. These will most likely be mobile.

The AAD is 20 per cent superior to PAC-3

How does one quantify capability ?? even with extensive knowledge of comparative systems !! If he is generalising one could say he is stupid, but is he referring to some specific matter like range or altitude of interception or hit probability ?

How did they come to that 20% figure?

Austin · Post by **Austin** » 23 Sep 2010 13:42

^^ I think they must be comparing known figures like range , altitude and kill probability of PAC-3 and AAD. Certainly in altitude of interception and range AAD outclasses PAC-3 , though PAC-3 is a faster missile with speed in access of Mach 5+ compared to AAD Mach 4+

PAC-3 it self is going through enhancement and they are working on PAC-3 MSE which besides other thing offers 50 % more range over PAC-3

I have a newbie question. Care to answer!

koti · Post by **koti** » 10 Dec 2010 16:08

I have a vague idea(rational to me) to detect the Stealth airframes.
Maybe this already exists or not feasible is something I am yet to read.

Its that stealth design essentially means that the Stealth AC makes sure that no radar wave is reflected to the source i.e., the radar emitter.
So its edges and surfaces are designed to deflect the radar waves at every angle except 0 degrees to normal.

So this means, if there are receivers located in different locations, some of them should be able to detect these deflected rays if they are looking at the required frequencies.

It gets better if we have a mesh of radars well spread and acting as a group of synchronized TR stations.

And of course this will not address the effects of RAM.

Kindly comment on this possibility(or otherwise).

^^ one of the propsed concepts is Multi static radar http://en.wikipedia.org/wiki/Multistatic_radar

makes sense, but it will mean looking for disturbances and anomalies and then infering where the target may be...

My understanding of stealth means that it would be not detected on radar.I felt would have these features

1.Will it show in the radar as a aircraft (meaning the exact cross section not the radar crosssection)
2.Will the radars will be able to track them for a missile lock either from ground/air ?
3.What people conspire is that some aircrafts can be identified visually(with binoculars) than radars.
4.And obviously electronically scanned radars are more capable in detecting stealth ones(instead of using multiple radars it creates multiple beams)

my two cents

There have been articles of weather doppler radars being able to pinpoint a moving stealth aircraft at lower altidues
I think it worked on the premise, of a lack of target return (where return was expected fm terra firma ) and this lack of echos was moving. if display settings were tweeked eg the anti clutter were set to actually show up a fair bit of clutter, contrast etc. A black blob depicted by lack of echo moved, highlighting a stealth aircraft .
These reports were available in tech journals extensively ( in the era of 1st gen stealth aircraft)
Do not hear much about it nowadays.

I am pretty sure softwear analysing the raw video could do jadoo with this pattern of lack of echos.
A powerful sat based doppler radar or even a high altitude AWAC could use this(in addition to S band or longer wavelength waves)

Sorry cannot link any articles as have read these articles years ago maybe somebody else read it too and could provide a link.

Reading about the Mumbai doppler triggered this off.
