Indian AESA Radar Developments

This is the 2nd VHF radar seen in recent months. Previously we saw the DRDO VHF-S band radar on a TATA HMV chassis.

We are stepping up our counter VLO/stealth game.

This radar seems to have decent specs:

VHF-band surveillance radar (VHF-SR) by the DRDO-BEL #TASL.
- 400km range
- Can Track up to 100 targets simultaneously.
- GaN TR modules

System has recently entered into field trials, marking a critical phase in its validation process to assess performance parameters such as low RCS target detection range, angular resolution, and tracking accuracy against low RCS targets under operational conditions.

Higher res version of the VISR-AX

Seems we're continuing work into truly multi-function arrays that can perform not only the typical radar tasks of transmit/receive but also perform communication (LoS comms using X-band) & passive sensing aka RWR-like functions using the same array.

In many ways this is similar in function to the kind of tech the US/Europe are working on for application on their 6th gen fighter programs. I won't be surprised if a version of VISR-AX will be implemented on the AMCA Mk-2.

I was wondering where this radar would be used. Turns out it is meant for the ISR plane:

I-STAR: India’s eyes in the sky? IAF set to get Rs 10,000 crore indigenous spy planes

India's Defence Ministry is set to review a Rs 10,000 crore project. This project aims to acquire three advanced spy planes. These planes will enhance the Indian Air Force's surveillance capabilities. They will provide detailed air-to-ground intelligence. This will enable precision strikes on...
economictimes.indiatimes.com economictimes.indiatimes.com

The defense ministry will take up the proposal of these STAR planes later this month, these planes will probably use the above radar.

"The I-STAR project involves procuring three advanced aircraft — likely from international aviation giants like Boeing or Bombardier — which will then be fitted with fully indigenous sensor and electronic systems. These onboard surveillance and targeting systems have already been developed and tested by DRDO’s Centre for Airborne Systems (CABS)." from the article

This is the VISRAX, developed by DRDO’s Bengaluru-based Centre for Airborne Systems (CABS). Engineered to be scalable across a wide spectrum of ISR (Intelligence, Surveillance and Reconnaissance) applications, VISRAX [Versatile ISR AESA X-Band] is a next-generation, software-defined Active Electronically Scanned Array AESA transceiver. According to DRDO sources, VISRAX will form the technological cornerstone of the airborne maritime surveillance radar destined for integration onboard the C-295-based MMMA (Multi-Mission Maritime Aircraft) and MRMR (Medium-Range Maritime Reconnaissance) platforms of the Indian Navy and Indian Coast Guard. Furthermore, the system is being actively proposed for a variety of emerging UAV-based ISR roles, reinforcing its adaptability and mission-readiness across domains.

50 km for 2 mt² target & 4 Km for 0.01 Mt² target..... actual detection range would be around 13.25 Km for 0.01 mt² target if one calculate.... Don't know why he quoted just 4 km.

Drones being small need repeated scanning/detection and a bit of identification process involved via software perhaps. That 0.01m2 means essentially a 10 cm x 10 cm object flying at quite low speed, hence signature would be quite different low tuned that would need clearance from any clutter/noise. At 10+ km will be harder to differentiate from clutter via radar software algo but as it comes closer to that range it can definitely be identified and IFF done.

Idk if someone shared it here already but while browsing LinkedIn page of Data Patterns I found some interesting things:

Looks like they Gan radar they made for Su 30, which they claim to have 2,700 TRMs.

1000034272.jpg
This looks like a row of TRMs in the form of LRU, probably for the Su 30 GaN AESA radar they made.

1000034271.jpg
They seem to have made a space object detection radar as well!!!!
