The first batch of Tejas fighter jets will be equipped with the Uttam radars. Of the 123 Tejas fighters that the Indian Air Force will get, 40 will have Israel’s mechanical radars and 83 will have Active Electronically Scanned Array (AESA) radars.

Defence Research and Development Organisation (DRDO) chairman Sateesh Reddy has told Times of India: “We will have the Uttam radar from the 21st Tejas Mk-1A.” This means 20 of the 83 Tejas will have Israeli AESA radars and the 63 will be equipped with Uttam radars. He said Uttam has performed better than anticipated in the trials.

Produced by Electronics and Radar Development Establishment (LRDE), a DRDO lab in Bengaluru, Uttam is a state-of-the-art AESA radar, which can track multiple targets and take high-resolution pictures.

Uttam’s project director Seshagiri P has said that the radar is being tested on two Light Combat Aircraft (LCA) and one executive jet. He told TOI that on the LCAs, testing is for air-to-air mode at present.

“The range of the radar should be almost commensurate to launch a BVR (beyond-visual-range) weapon; it’s specified to be so. But we’re getting a range that’s better than that. We are a couple of sorties away from starting a joint evaluation. After this, it will be ready for user evaluation,” he said.

Uttam’s three basic modes – air-to-air, air-to-sea, and air-to-ground – have been tested on the executive jet. “The same needs to be ported on LCA and checked for performance. There’s a fourth mode called navigation terrain avoidance, weather mode (rain-bearing clouds),” he said.

Producer of Tejas, Hindustan Aeronautics Limited’s (HAL) Chairman and Managing Director R Madhavan has said they have placed orders for 20 Israeli AESA radars and Uttam should be ready shortly thereafter.

He said their target is to increase indigenous content in Tejas from 52% to 65%, and this will help in achieving that goal. The move is in tandem with the government’s push for promoting indigenously-developed defense equipment.

Does it have SAR? What’s the SAR resolution? What about other detailed Specs?
According to the photos available it has Around 400-450 TRM modules…which would make it the AESA with the least in the world. JF-17s radar has 1100+ for 1/3rd the price.

1100 T/R modules is a good number?

SAR? I don’t think so.

1100+ TR modules on JF-17? It looks better than Gripen-E and Rafale.

It does appear that JF-17 would be quite ahead compared to Tejas. That too at one third the price.

You shouldn't have replied to him bro. They make fun of our gods. Hindu population and it's temples both are on the verge of extinction in Pakistan and Bangladesh
Nope 🤭

Hindu population in Pakistan has grown at a faster pace than in India

Uttam needs to be tested with missiles loaded and fired etc. So let's not jump the gun. Though progress is impressive from news ticking on with software programming for 3 modes done and initial flight tested with air to air mode flight testing done.
Air to Ground mode rigorous testing is being done now and air to sea has seen initial testing.
We need to start parallelly the next phase with weapons test.

it's not good for us. India is making rapid progress. There are so many projects and money is invested on right projects. Pakistan should also try to make radars.

It appears that your fears are unfounded. Pakistan has already started project AZM. There is a dedicated thread on PDF about AZM. It seems to be doing very well.

Another false flagger in the house. It was evident when you said azm seems to be doing very well 🤣

Mate you're supposed to put up the flags of your origin country and where you live...not who you're primary adversary is

My flags are perfectly in place and I am proud of them.

It appears that you haven’t visited the thread on AZM. Turkey is already yearning for a partnership with Pakistan on 5th gen fighter. Would it be so if Pakistan was not doing something good. Let’s keep that discussion on that thread.

As far as Uttam goes, there are only reports of trials. Real numbers and performance is not yet available. Till then, a little restraint in claiming sky high performance may not be a bad idea.
