This is the above work , some SAR system

DRDO soon to start the realisation of 2 X-band air borne Imaging Radar for Ground Testing. The test radar will have 512 TRMs. Not sure for which platform. pic.twitter.com/jxhnaCDKeD

MMW seeker mk-2, Lead integrator partner company sought.

2. Selection and acquisition of assigned targets / jamming sources (HOJ)

So this seeker with other enabling technologies when incorporated into our AshMs will allow us to target group of ships including aircraft carriers if so desired & if so enabled for

Uttam AESA Update as shared by the representative-

Tejas Mk-1A> improved GaAs based Uttam Mk.IA
LCA Mk-2 > GaN based Mk. II

A lot of things however have to be validated before a jump to the next level. pic.twitter.com/Q8WTUMV0iF

So my guess towards Su-30UPG getting GaN AESA right from word go is coming true. Su-30UPG's Uttam MK-3 was going to be derived from scaled up LCA- MK2's Uttam derivative.

Under Modi we're seeing quantum jump in our indigenous defense capabilities. Jai Hind

So, this is the AAU which is present in INS Anvesh.
They are using a very generic model and image of Norwegian Navy warship for representing it.

Slightly old, from August 2021 but a decent presentation+discussion

What will this radar be used for? At present only have this part.

 

[marich01]

Seems they have finalised QRSAM radar QTRMs for C & X band. Two trials are envisaged over next 18 months. Below is the C band QTRM. 240 for C band, and 384 for X band.

Strange.

When the system is ready for the induction then why now they are planning for the trials?

Yesterdays sow was mainly maintenance related , ie keeping the radar & 8x8 vehicles in ready condition, there was a para like this in the 3rd screenshot.

Simulator tender is up from LRDE.

 

[marich01]

There is a solid radome tender, just the radome. It is mentioned to be used for an L band radar, on a concrete platform. The radome is of 23.5-24 meter dia. Seems like those white domes you see in weather radar station (visually).

 

[marich01]

Came out today, we might be getting closer after all.
