First DRDO AWACS rolls out

[Kinetic]

As I meantioned in earlier discussions about that, I think it's just a compromise to the design of the aircraft itself. Some aircraft use wingtip pods to house the ESM and other parts, the EMB 145 has winglets, which rules out carrying heavy additional pods. The size of the blisters depends on the ammount of techs integrated into it, interferometry arrays and other ESM / CSM sensors are clear, but there will be more.

The original Prasun Sengupta article said:



TRISHUL: CABS’ AEW & CS Detailed


The article is from 2008 and not sure if the Chaf and Flares will be mounted under the winglets, but it gives a hint on what systems, sensor and countermesures might be included in the blisters.

Good catch, it is most probably interferometer antenna array for direction finding (DF). Such multiple antenna array with non-uniform spacings is required for high accuracy without ambiguity over large band-width. But these technologies being developed long ago by DRDO, I think they have done something more in these arrays.

Any idea what gonna be the range of the radar and IFF? Are they related?

The L band IFF has a 500km range at sides (250km at front & back).

DRDO’s Active Array Antenna Unit (AAAU) or the Primary radar is designed to have a range of 200 kms for 2 sqm target as per the OR by the IAF. In international comparison table it translates to 5 sq meters target or RCS can be detected at a range of 300 kms in normal mode of operations and 375 kms for extended modes, i.e. while not looking 240 degree all the time.

Which would confirm once again, that it is less capable as the Swedish Erieye system, but a good start for the first attempt!

^Hang on there. The erieye has a detection range of about 350km. If the DRDO awacs is 300-375, how does that make us inferior? If anything we're as good. Furthermore, the erieyes in PAF service are not mid air refuellable. Neither do they provide 360 degree cover.

First of all, I'm talking only about the radar system, not the platform, or additional features!

Secondly this is what ganimi kawa said:

The latest Erieye system is given with 350 to 380Km for fighter sized targets and has a can detect targets in a 300° field. The specs given for the DRDO radar systems looks similar to the older Erieye system, that was used on the Saab 340 before, but as I said, pretty good for the first attempt

In 240 degree mode, it does 300km.
In extended mode, it does 375km.

Yeah, the range of IFF is 520 km but the radar should have more than that range considering the size of AAU. Its 8.2 m.

Not advance. Need to full separate hall or area to operate AWACS system. Including facility to have 5 military satellite that can be used to check the suspected area. I guess we lack co ordination.

This is taken from Aero India not inside the AWACS.

The AWACS will have five WS.

Looks pretty advanced to me, compare it with the latest Boeing 737 AWACS:

I don't see a big difference for the operator, just that they have more, because the aircraft is bigger.
