The Indian organization DRDO (an approximate analogue of Rostec) confirmed the existence of the Virupaksha program. This is an ambitious project that provides for the modernization of Su-30MKI fighters by installing modern AFAR radars on them.
As explained in the DRDO manual, the new radar should have advanced capabilities, while simultaneously carrying out aerial surveillance, targeting and weapon control.
One of the most notable features of the project is the intention of the developers to use the antenna positioner in the work of the radar. This mechanical device will allow you to change its position, directing it both in the plane of the angle of the seat and in azimuth, which will significantly expand the field of view of the aircraft. This will significantly improve the overall performance and increase the versatility of the radar.
The Laboratory of Electronics and Instrumentation (LRDE) is currently developing the Uttam Mk2 antenna with a positioner that provides the ability to rotate up to ±90° in azimuth and ±20° in elevation.

As noted, the Virupaksha project will allow replacing mechanically controlled antennas and high-power transmitters (operating within the framework of the current "hybrid" radar with passive headlights) with an electronically controlled array:
It is reported that the Virupaksha radar will be installed as part of a more extensive modernization of the first batch of Su-30, consisting of 84 sides. As it is emphasized, previously, only Chinese Su-30s received radar from AFAR.
