^^^It would be very interesting to see what sort of pulse widths they can generate with these newer GaN designs.

Yeah, I don't think they'll reveal many details on either proposals. From what we know, Northrop Grumman has been flight testing and demonstrating its prototype sensor for a number of years now, and Raytheon is expected to have its design based on the Navy's AAS which it is currently integrating on the US Navy P-8A.

Two very interesting new radar programs from LRDE have publicly emerged (public domain).

One is an Adaptive Radar Test Bed. Basically adaptive algorithms that can dynamically change to finesse performance.

Another is a Dual Panel Long range Multi function radar. IMHO, this is either a testbed for a proper 4 panel one (eg Naval applications like the Barak-8 unit) OR a testbed for a BMD oriented system. Time will tell.

Both appear to be AESA units.

Either ways, as predicted by yours truly, DRDO has the building blocks in place for long range systems and advanced systems and is moving on that path.

Karan ji, that sounds like BMD radar. Swordfish is just a customised green pine, so after MPR and AWACS, it would be the logical next step.

Its a tropo scatter system.

Meanwhile, there is yet another new radar, the mountain radar - from the below, likely variant of Aslesha Mk-2.
http://www.aeromag.in/Magazines/9338378845.pdf

BEL’s Chennai Unit manufactures
the Compact Multipurpose Advanced
Stabilised Platform (CoMPASS), which is
a highly stabilised, multi-sensor, electro-
optical payload having Electro Optic
elements like Thermal Imager, Colour TV
Camera, Laser Range Finder/Designator.
Till now, the Unit has supplied these
systems for Advanced Light Helicopter
and Mi 17 platforms.
In the field of radars, BEL has successfully
inducted Rohini’s variant 3D-Tactical
Control Radar in the Indian Army and
Revathi in the Indian Navy. Similarly, the
3-D portable radar, Aslesha, is a great
success. BEL has secured business of
its variant called Bharani-II. BEL is also
developing the mountain version of
Aslesha radar, Aslesha Mk-II.
New developments with DRDO are
in the field of 4 Dimensional, Medium
Range, Fully Active Phased Array Radars
like Arudhra Radar, Mountain Radar
and Ashwini Radar. BEL is also working
with Thales through the Joint Venture
Company, BEL Thales Systems Limited,
on the development of Long Range High
Power Radar and Multi Function Radar,
Pharos.
BEL has added another feather to its
cap with the development and successful
trials of Weapon Locating Radar (WLR),
a field artillery radar system capable of
locating enemy artillery batteries or shell-
firing guns, mortars and rocket launchers
with great precision and guiding own
artillery fire to neutralise the enemy
targets.

Is the Pharos a replacement for Flycatcher radar ?

Karan M question...

I was reading up on Aslesha (3d) and Bharani..

The Bharani (2D) is being used by the AAD.
ASlesha is for the IAF.

Both of them have more or less the same function..low level intrusion detection.

So why a 3d version for IAF and 2D version for AAD?

Design trade offs based on mission requirements and cost.

The Bharani is for low velocity targets such as UAVs and helos. Primarily for detection and less for tracking. It has a beam that is 6 deg AZ and 35 deg EL. The Aslesha is an S-band phased array, with a pencil beam that is accurate for tracking fast moving targets. Since these are low cost light-weight systems they could be networked together where the Bharani could make a quick detection and the Aslesha would then track accurately.

Sachin saar they saw the Aslesha and now want a 3D radar. So after Bharani Mk1, there is now a Bharani Mk2 which is none other than an AAD version of Aslesha for Army, its 3D etc. Basically, the main advantage of Bharani was a lighter antenna, but the heightfinding advantage of the Aslesha and its more precise features (as Mort pointed out) means the Army is now moving over to Bharani Mk2/Aslesha.
