AesaRadar ” Uttam ” for Tejas MK-II been tested Air-to-Air mode (link)

The state-run Defence Research and Development Organization (DRDO) which has taken up the development of flight control radar for fighter aircraft with 100 km range and multi-mode operation.AESAradar development which has been started under Project ” Uttam ” which is a Sanskrit word for ” Best ” .

Realisation and calibration of prototype Active Aperture Array Antenna Unit (AAAU) has been completed with indigenous TR modules .DRDOcurrently has placed Airworthy radar processor and exciter receiver on a high rise platform in Mechanical Scanned Array (MSA) configuration for validation of various algorithms and wave-forms of the fie control radar .

Software development for air-air sub-modes have been completed andDRDOis testing Radar in Air-to-Air mode but crucial software block testing will be development of software which will allow air-to-ground modes which is crucial for aircraft to carryout high resolution mapping, multiple ground moving target detection and track, combat identification, electronic warfare, and ultra high bandwidth communications.

Project is still a long way from completion andDRDOstill has not clarified if Israeli help has been sought in its development nor what level of indigenous content will be used in the radar . work on indigenous TR modules started in 1998 after successful development , Radar development was cleared in 2011-12 period . First Tejas MK-2 Prototype will take to sky by 2018-19 and will enter Production by 2022 and it is expected that AESA Uttam will be ready and enter Production.

What will be the range of "Uttam"?
Why will it take 3-4 years for the prototype to fly , when most of technologies have been tested?

Simplely because the aircraft is yet not have a protype on which this radar can be tested.

And for the range is about 100 km though its small but a good start.

The Mk-II is also likely to sport an indigenously developed active electronically scanned array (AESA) fire control radar currently under development by DRDO's Electronics and Radar Development Establishment (LRDE) under Project Uttam. Hardware has already been realized for this radar which has a range of 100 km and rooftop testing is underway. Apparently December 2015 has been set as a time for both DRDO & the IAF to take stock of the maturity of this radar since the IAF wants clarity on the radar front for the Tejas Mk-II. Though the Uttam AESA currently weighs 120 kgs which is some 40 kgs more than the current MMR, there will be no problem in integrating it with the Mk-II which can easily carry a radar of this weight. So if the end-2015 stock taking exercise satisfies all stake holders, Mk-II will definitely feature LRDE's AESA once it completes development. In fact this radar if successful is also intended as an upgrade package for the IAF's Jaguars and Mig-29s and the Indian Navy's (IN's) Mig 29Ks.

Today neither ADA nor the IAF want to jump headlong into the Israeli offer on the EL/M-2052 for the Mk-II especially since Project Uttam is progressing quite well and LRDE is confident that it will be able to deliver a good product within the stipulated time frame. Specifically LRDE's successful development of an airborne AESA used by DRDO's AEW&C aircraft, two of which are being inducted into the IAF has enabled it to master look down modes for the Uttam AESA as well. Dr Tamilmani says that he is taking monthly reviews of this radar and firmly believes that it will succeed. The Mk-II will also see the incorporation of a new on-board electronic warfare suite which is being jointly developed with the Israelis.

The glass cockpit for the Mk-II is going to be new as well. For one it is going to feature bigger 8 x 12 inch displays rather than the 5 x 5 and 6 x 6 inch displays currently featured in the MK-I cockpit. A prototype of the Mk-II cockpit already exists. While the initial lot of MK-II displays will be imported, in the future Samtel will supply indigenously developed ones.

If the radar is developed in 3-4 years then looks like LCA MK2 will surely have it

Why not test it on mk1... does m2 bigger that mk1 of tejas ???

It's good and LRDE Patent and Uses Gan based technology aswell 100km Aesa is very potential in comparison to PESA & Mechanical Radars.it will progress as project uttam get mature

But having only 100km range isn't enough right?

Link to the article please? Don't say its again idrw!!!!

Arre bhai, pehle Tejas Mk-1 tho complete karo!

Our radar techs is one of the areas where DRDO made good progress. Now we have varieties of AESA as well as other radars.

Arre bhai, pehle Tejas Mk-1 tho complete karo!

It will be inducted into IAF in March.

Thanks a lot for sharing. mkII going to be a masterpiece.

It's AESA, the technology Itself is very potent almost impossible to jam its signals In comparison to mechanical Radars.Currently it uses 3-4KW peak power APU & 400-500 TR module's it will surely get mature with project development Cycle

Hi,
That is probably because it is taking some time for the LRDE to develop it's air-to-ground modes,as they are inherently more challenging vis-a-vis air to air modes.For instance in A2G mode you need a lot of things from your radar like GMTI,SAR,Space time adaptive processing etc.Thankfully LRDE has gained enough experience with these modes after working on LC's slotted planar MMR and indigenous AEWCS. We can expect to see L273 radar flying in couple of years on test beds

@Donatello

Hi,
Does PAF have any plans of acquiring AESA for JF-1 later variants?and what will be the likely source?
