Do you people have any plans to use possible domestic platforms for your AWACs programmes as well? Any projects you have that could act as a domestic platform?
must wait for 10 more years though lol.

As you can see the interferometer antenna is small enough to fit on the wingtip

Thx girl but genius is too much!![]()
So the only reason why you are speculating here, is that the Saab 2000 has ESM pods on the wingtips? But you did realised that the DRDO AWACS has winglets right?![]()
Moreover, why don't you try it with simple logic? IF those conformal antenna would be radar arrays, they would cover only the same area to the sides, that the twin array on top is covering anyway and we still would have the same blind spots to the front and aft field, so it's totally useless!
First, you do realize when I called you a genius I was being sarcastic.![]()

Not location but size and purpose, interferometer arrays are typically classified as Very Small Array, small enough to fit on the wing tip of a fighter as a mater of fact Gripen has two on its wingtip.
It is a conformal array, conformal antenna have its T/R modules arranged to 'conform' to almost any shape desired. See below image, clearly T/R modules will be placed by DRDO for improved coverage aft and fore to the side
I'm certain you won't agree and will continue to present some retarded arguments to justify a huge interferometer array on the side - it should be good for a few laughs.

Any chance that these AWACS could be used on an aircraft carrier? Forgive me if that sounds like a stupid question.
Of course, because I backed my points with sources of the DRDO AWACS and you (as usual)
. Let me use your own evidence against you (see below).
The recently installed ESM array is prominent. It uses a dual baseline interferometry scheme for precision DF.
AN/AYR-1 ESM system (United States), Airborne electronic warfare (EW) systems
Type
Airborne Electronic Counter Measures (ECM), Electronic Support Measures (ESM) system.
Description
The AN/AYR-1 is an advanced ESM system which is part of an upgrade to US Air Force and NATO E-3 AWACS aircraft. The system undertakes passive interception, identification and analysis of radar and radio signals. The antennas are installed in a blister on either side of the aircraft, just aft of the cockpit, and in nose and tail arrays, to provide 360° azimuth coverage.

@ DBC
Again you are trying to prove one speculation with another one and still can't provide a single source that says anything about an AESA radar array to provide 360° radar detection in that blister!
...other conformal antenna arrays located around the aircraft will provide better coverage than is possible with Erieye.
Also it's not only the livefist graphic that shows that this location on the DRDO AWACS is for the ESM antennas, also the following brochure does it (check the pic on the lower right):
*DaimlerChrysler Aerospace:*Contract for NATO E-3 upgrade placed January 1993; designated Mod Block 1; includes new colour displays, Have-Quick secure radios Link 16 (JTIDS) datalink and AN/AYR-1 Electronic Support Measures (ESM); initial two aircraft under 1993 contract; follow-on order for remaining 16 modifications placed mid-1993; all retrofit work by DASA in Germany. All Mod Block 1 activities completed in November 1997.
Did I say 360° radar detection? I said....
The word I used was better coverage, I don't expect the 'new' Indian AEW&C to have 360° radar coverage,
clearly T/R modules will be placed by DRDO for improved coverage aft and fore...

First you're comparing the sensors of a much larger and older system (E-3C)
The area you're referring to as the location of the interferometer array is closer to the passenger door and not near the wing.
):improved coverage aft and fore
The only thing you've proved yet again is that you're closed off and unable to accept new ideas or an alternate point of view.
When you have a point ok it, but you haven't and are just speculating and all available sources are proving you wrong, so why should I accept it then?
One of the star attractions at the Defence Research & Developments (DRDO) pavilion in Bengaluru were various components of the indigenous airborne early warning and control system (AEW & CS) that is now under development. It may be recalled that in a path-breaking development, Brazil and India on July 3 last year had inked a US$210 million agreement to jointly develop an AEW & CS for the Indian Air Force (IAF). The agreement was signed by Dr S Christopher, Director, of the DRDOs Bangalore-based Centre for Airborne Systems (CABS), and Luis Carlos Aguiar, Embraers Executive Vice President (Defence and Govt Markets), in the presence of Marco Brandao, Brazilian Ambassador to India, and M Natarajan, Scientific Adviser to Indias Defence Minister and Secretary, DRDO. India, incidentally, had earlier acquired five EMB-135BT Legacy executive jets, under a Rs7.27 billion contract with Embraer, to ferry VVIPs around the country and abroad. Under the latest deal, Embraer will modify its EMB-145 regional jet aircraft to carry two types (S-band and L-band) of Active Array Antenna Units (AAAU), developed by the CABS, on the aircrafts fuselage.
The AEW & CS roof-mounted S-band pulse-Doppler active phased-array radarbeing developed by the DRDOs Electronics R & D establishment (LRDE)--will operate within the 2GHz to 4GHz bandwidth. The 8 metre-long, 900kg antenna (using 1,280 phase shifters) will be mounted on the upper dorsal spine of the aircrafts fuselage. The radars dorsal unit (DU) will include the carbon-fibre radome, antenna array, RF distribution network, and 192 transmit/receive modules that will be cooled by ram-air. Each such module will comprise a power amplifier for the transmitted microwave signal, low-noise amplifiers as front-ends for the receiver channels, and phase shifters for accurate control of the signal phase in both transmit and receive modes. The AESA radar will provide 270-degree airspace surveillance coverage and have an instrumental range of 450km and detection range of 350km in a dense hostile electronic warfare environment. For detecting hostile airborne aircraft, two mean antenna scan rates of 12 degrees/second or 3 degrees/second will be used, while a scan rate of 3 degrees/second will be used for detecting terrain-hugging or sea-skimming cruise missiles. Warships will be detected using a low-PRF without Doppler filtering. An adaptive radar control mode will control beam scheduling to share the total available time between search, confirmation of detections, and track updates.
The avionics suite will also include an L-band IFF transponder, as well as twin side-mounted L-band AESA antenna arrays that will be capable of locating and tracking targets out to 240nm while the aircraft is cruising at an altitude of 40,000 feet. In addition, these arrays signals will be less attenuated by bad weather, and will not be restricted to narrow-beam operations.
Are you prepared to admit you're wrong? The Indian AEW&C has two types of AESA radar. The S-Band radar is roof mounted, while the L-Band radar is side mounted.
Any more silly arguments?![]()
The AEW & CS’ S-band pulse-Doppler active phased-array radar will...provide 270-degree airspace surveillance coverage and have an instrumental range of 450km and detection range of 350km in a dense hostile electronic warfare environment. The radar’s optimum performance (with very low sidelobes) will be over the 120° azimuthal sectors on each side of the aircraft...
...The radar will also include an L-band IFF transponder. (fullstop!)

Another component will be the ESM suite that will combine the radar warning receiver and countermeasures dispensers with interferometer antenna arrays, a missile approach warning system, laser warning system, defensive aids controller, and a display-cum-control unit.
P.S.
To refer to this one again, the left pic, shows the EMB 145 AWACS like it is available from Embraer itself, the right pic shows the EMB 145 DRDO AWACS, inclulding the airfame changes (refuelling probe, SATCOM, new radar array, additional side blisters for ESM) and that's what the brochure that I provided shows also (the graphic on the lower right showed the changes that the DRDO AWACS will have).
When you have doubts about livefist, how can you take this site that only mixes reports from other blogs as reliable?
Here is the original article that Prasun K. Sengupta wrote on his blog:
TRISHUL: CABS AEW & CS Detailed
So besides that this article (the original) is just anther source that confirms no radar detection to the front and back areas, it shows the radar will include an L-band IFF transponder. The whole part about twin side-mounted L-band AESA antenna arrays in your source on the other side, is just added and was never mentioned in the original article!
Also interesting for you should be the part of the ESM suit:
This should explain why the blisters needs to have this big size, because it includes way more sensors, antennas and other parts, just as I told you before.
"Another component will be the ESM suite that will combine the radar warning receiver and countermeasures dispensers with interferometer antenna arrays, a missile approach warning system, laser warning system, defensive aids controller, and a display-cum-control unit."
It's rather amazing how you proved yourself to be completely wrong about all your claims!

The IAF is also encouraging the DRDO to devise indigenous AEW & CS solutions. It may be recalled that in a path-breaking development, Brazil and India on July 3 last year had inked a $210 million agreement to jointly develop an AEW & CS for the IAF. The agreement was signed by Dr S Christopher, Director, of the DRDOs Bangalore-based Centre for Airborne Systems (CABS), and Luis Carlos Aguiar, Embraers Executive Vice President (Defence and Govt Markets), in the presence of Marco Brandao, Brazilian Ambassador to India, and M Natarajan, Scientific Adviser to Indias Defence Minister and Secretary, DRDO.

Under the latest deal, Embraer will modify its EMB-145 regional jet aircraft to carry two types (S-band and L-band) of Active Array Antenna Units (AAAU), developed by the CABS, on the aircrafts fuselage.
Not really, it is the same source, just a newer article but based on the same old points, but now integrates the second part of the Trishul article as well:Here is another source
For self-protection, the AEW & CS will have on board a fully integrated defensive aids suite (housed within two outward protruding fuselage sections) that is now being co-developed by DARE and EADS Defence Electronics that will include multi-spectral optronic sensors and an ESM suite, designed for the protection of aircraft against infra-red/laser-guided MANPADS)...

And it just cracks me up that you think the side "blister" houses the interferometer array,MAWS and countermeasures dispensers. Placing a countermeasures dispensers in line with the aircrafts engine is a retarded notion just like your posts.
This will in turn be fully integrated with wingtip-mounted lightweight chaff/flare countermeasures dispensing systems...
...the ESM suite that will combine the radar warning receiver and countermeasures dispensers with interferometer antenna arrays, a missile approach warning system, laser warning system, defensive aids controller, and a display-cum-control unit
