You are comparing apple with oranges here, a bvr races towards its target, and its range is defined as the distance covered by it until the motor burns out in a certain flight path configuration. It still needs guidance from fighter radar to close in before it can turn on its own radar and track the target itself for the kill. That is why the range of radar should outmatch the bvr missile range to effectively guide it to its target.
So?? Does that not mean Tejas has >120+km radar range?

If Tejas Uttam radar has a ~100km range then how to acquire weapons-quality lock on bogey & vector Astra with 120+km range up to the point where it goes pitbull?

Should? Yes. Must? Technically no. Technically the fire control needs to come for a sum total of the burn distance- a part may come from fighter and remaining from the missile's seeker.
However it's a pretty naive assumption that IAF will go ahead and select a radar with capabilities less than the one it already has planned to make Operational in other units of the same aircraft. Also, that the development agency that has developed an AWACS platform will offer such radar after 3 years of testing

Uttam aesa performance has been benchmarked against elta 2052. And uttam is found to be equal if not better than elta. Elta 2052 itself beat Thales aesa offer from France.

This performance was derived from GaS components. And now GaN components are being produced. Which will further improve performance.

In real world uttam can not only guide astra / mk1/ mk2 / Derby ER. But it can also guide meteor successfully too. No one will disclose true range but published ranges are very very conservative.

Uttam radar scaled for su30mki will be a beast and will be much much more powerful than current Rafale radar.

Performance equivalent to Rafale aesa could be realised in MWF sized aesa itself.

I think that Mk1A, Gripen E, Rafale all have rather small radars - less than 1,000 T/R modules. Last time I looked at Typhoon AESA development (years ago) it was intended to have more than 1,400 T/R modules. Does that mean the Typhoon AESA should be much more powerful? In addition it uses a swatchplate widening its 'field of view'.

If all these radars use similar components then radar with more T/R modules will be more powerful. It also depends on how much electric power engine can output and how aesa is cooled. On those parameters too typhoon is ahead .

But a GaN based radar could match or exceed GaS based aesa performance even with less T/R modules.

Hence I said that MWF radar could match Rafale level performance ( unless Rafale is also updated with GaN based radar in future).

And that's why su30mki radar based on GaN aesa will beat them all barring F22 /f15 only.

It's GaAs not GaS both are different

Hey guys. I guess Tejas could finally win The Malaysian Tender. What do you all Think about it?
Now only 3 Aircrafts are Left in Malaysia's tender:
Fingers crossed, I am praying that Malaysia will be the First Export customer most Probably in my opinion
Its either gonna be KAI FA-50 or M346.

Any reason for saying that Tejas will not be selected? Price? Performance? Availability? Because HAL has a reputation for being late? Because it is Indian (politics)? Because of concerns about support?

No. Its inferior in some aspects like Radar will be more Superior on The Tejas. Also LCA Tejas has access to better and More Capable Missiles like Derby ,R-73 etc. The block 3 JF 17 is not going to be like absolutely better than Tejas mk1a or at the Same level,JF 17 block 3 is Decent and it's definitely a Good Aircraft for its price(can't deny that) but Still Tejas mk1a is better in some Aspects. Block 3 will be a good Fighter with PL-15 missile.
JF17 B3 is nowhere close to Tejas MK1a.
