Hello sir I want to know about Uttam AESA Radar in DRDO so here can you please give me its details ?

Hey as per my idea An Active Electronically Scanned Array (AESA) is an active antenna and here I am giving you its details

Electronics and Radar Development Establishment
Electronics and Radar Development Establishment (LRDE) is a laboratory of the Defence Research & Development Organization (DRDO). Located in C.V. Raman Nagar, Bangalore its primary function is research and development of Radars and related technologies.

Uttam AESA Radar
Uttam AESA is an indigenously developed active electronically scanned array (AESA) fire control radar.
It is being developed for the LCA Mk2 and Mk1 (presumably Mk1s will be upgraded with the system) and also other aircraft upgrades such as the IAF's Jaguars and MiG-29Ks.
Hardware has already been realized for this radar which has a range of 100 km against small fighter sized targets and rooftop testing is underway.

Though the Uttam AESA currently weighs 120 kg which is some 40 kg more than the current MMR,
There will be no problem in integrating it with the LCA Mk-II which can easily carry a radar of this weight.
It is a 3D radar for fighters, a MMR follow on,

Advantages
The inherent advantages of the active electronically scanned array (AESA) radar are the obvious inertia-less scanning and the minimal feeder loss as no lengthy feeder cables are involved.
Unlike in the MSA radar, the AESA radar has the impudence to perform even with failure of some of its radiating elements.
