Same QTRM and same in number, peak power transmitted is ~8.9kw.
Avg is 880w.
AMPL is manufacturing most of it (expected I guess).

Specifications for Mk2 Uttam radar
It's GaS TRM.
Looks like same radar for Mk1 & Mk2.

Maybe for initial prototypes. Since MK2 is litetally a next decade program, the final production version having a GaN variant is a given.
Again..
But i agree with you..
This is direct adopted mk1A radar to Mk2 prototypes..
Seems like from Day 1 it ll fly with aesa.
Definitive radar will developed or upgraded for mk2 production.
Which radar was of dimension 6 meter x 6 meter x 0.3 meter kind ? I forgot exact but there was one in the past 2 years. Well the AAAU testing of the same , assemble and testing jigs etc are sought.
You talking about IN's LRMFR, bro?
Looks like a lot of its features like Antenaa Control Unit etc. are fused into its main-circuit for improved detection of low-speed targets against ground/sea-clutter. Hence no requrirement of separate BCU.
But I could be wrong here. Maybe @Gautam & @randomradio could chime in here
Yeah most likely that LRMFR aaau, dimensions match. Testing to begin after the jigs are made.
BCUs & ACUs are power control units. They control when, where & how much power is transmitted to the antennas. They can also act as frequency, range & mode switching equipment.
ACU based radars are generally more agile & can do the switching faster. But they are limited by how much power they can transfer & also heat up a lot quicker. So not great for larger radars. BCU based radars can operate in a huge bandwidth of power & are generally easier to cool. But they are bulkier & not great for applications that have a limited space & power constraint.
The Virupaksha will be pushing the boundaries of ACU's capacities. But LDRE thinks that with GaN transistors & a new vapour cooling system they can still have an ACU.
Wonder what spec would the new LRR, VLRTR be as that would be replacing the swordfish etc.

I wonder what's stopping the DRDO from navalizing the Arudhra radar as a replacement for Fregat/Top Plate on the Delhi and Talwar classes. The navy specific modes could probably be ported over from other programs.
It is already 'navalised', it is the Indian Navy that has to show interest in a smaller (compared to 6m SBR) S-band radar to replace Fregat on older ships. DRDO has already moved to an improved version of Arudhra MPR for mountain radar.
If it's true, then I'm not surprised. GaN is still in the works, and GaAs is better for standardization.
You can have 10 W GaN TRM too.
For a change it is good to hear ISRO talking on defence capability part.
The current global situation, with the ongoing war between Ukraine and Russia and other conflicts, poses a significant threat of a third world war. This is why every country is preparing itself, and India is no less than others in designing and preparing a robust shield for its own defence," said SV Sharma, Deputy Director, ISRO, after a National Security Summit organised by Sigma 9 Aerospace Defence in Hyderabad.

There is some 8 x 8 modular and scalable AAAU being made by LRDE , based on planar tech ie flat panel. Wonder what is it for.
Which AShM will use this?
Brahmos uses the X-band monopulse seeker from Data Patterns. Will they get X-band AESA seekers eventually? Or maybe the NASM-MR will use this seeker.

This was in the Aero India or defexpo brochure.
Anyway talk of Voronez radar being bought , maybe they will try to integrate features into own VLRR programs ?
