Indian AESA Radar Developments

DRDO is working on GaN based wide band arrays for ESM/ECM. This is a part of the naval Shakti EW suite upgrade program:

Various radar micro-electronic components. Among them the 130W GaN HEMT:

Top shelf shows a GaN based 64 channel S-band plank. Probably used in the LR-MFR. Bottom shelf shows the internals of the new APS radar:

16 & 32 channel X-band plank for some large X-band radar:

Which X-band radar? Virupaaksha ?

Very hard to pinpoint. They sometimes realise common lru and reusable/scalable subsystems via separate contracts like project AMTR (development and testing simulation separately) below and unless specifically mentioned, one would need expert knowledge to pick through the hints.

Data Pattern's stall was a surprising one. They had new AESA radars for Su-30 MKI, MiG-29K, Dornier Maritime, and two different radars for ALH. They stopped me from taking pictures.
  • They are claiming that the radars on display, MKI and MiG-29K, are their own design, independent of DRDO.
  • The MKI radar has a rotating repositioner. They demonstrated the repositioner working, and it was shown rotating 70 to 100 degrees. (I think, The picture that leaked on the first day is of Mig-29k not MKI).
  • Dornier Maritime (Do-228 MPA) radar is under flight testing. Its called Kshitij.
  • One ALH radar is for Naval Dhruv UHM helicopter with is under development by HAL.
  • Additionally, there were high-band jammers which they also claim are independent of DRDO offerings.
  • BrahMos Seeker, made by them, was also on display. They claimed it is already in production. I reminded him that it has yet to be test-fired. He looked puzzled.

Alternative to BARS radar on Su 30MKI. Please note, here the antenna can move left to right and up as well as down, whereas the original BARS antenna is fixed.A system by Data Patterns.

This radar has the best looking AAAU of any Indian radar till date:

And the AAAU is also as scalable as the Uttam.

LDRE has done AESA ToT/industry handholding right & kudos to Data Patterns for rapidly absorbing the tech.
