J-20/J-10B/J-11D have radars from NRIET, while J-16/J-15 use radars from 607th Institute.

1): Are both NRIET and LETRI producing 4th generation AESA radar now ?

2): Based on your own estimate --
How many AESA T/R modules does J-11B & J-11D have ?
1760 or 1856 T/R modules or even more ?


3): What kind of packaging technology do they use ?
Do you have the pictures of T/R packaging from NRIET and LETRI ?

4): What kind of T/R modules cooling system do they use ?
Is that Liquid Nitrogen cooling system ?
Do you have the pictures of T/R modules Cooling system from NRIET and LETRI ?


5): Is that possible to turn off J-11B and J-11D radar and network them with KJ-2000 or KJ-200 AWACS fleet ?


indigenous domestic Chinese processor named Spirit Chip # 1 (Hun-Xin Yi-Hao 魂芯一号), which is more than six times more capable than similar western chip in 2003

6): Does this Spirit Chip # 1 (Hun-Xin Yi-Hao 魂芯一号) help miniaturize the T/R modules ??


Many thanks for all your help in advance.

It's Flankers vs Gripens in China's first joint aerial exercise with Thailand!

I doubt radar generation corresponds with fighter generation. That being said, the J-20's AESA radar has been built by NRIET already. Don't know about the J-31's AESA radar, though.

2): Based on your own estimate --
How many AESA T/R modules does J-11B & J-11D have ?
1760 or 1856 T/R modules or even more ?

I am fairly certain that the J-11D's array will have more than 1760 T/R modules. One of the reasons why NRIET was chosen over LETRI for the J-10B's AESA tender was because it could pack more channels into a small radome. Hence, given that all Flanker derivatives have the same radome size, a radar from NRIET should have more T/R modules than LETRI's 1760-channel radar aboard the J-16. J-11B does not have AESA yet.

3): What kind of packaging technology do they use ?
Do you have the pictures of T/R packaging from NRIET and LETRI ?

Sorry, these haven't been revealed yet.

4): What kind of T/R modules cooling system do they use ?
Is that Liquid Nitrogen cooling system ?
Do you have the pictures of T/R modules Cooling system from NRIET and LETRI ?

I think both NRIET and LETRI use GaAs transistors, but this could have changed by now. Cooling systems are secret.

5): Is that possible to turn off J-11B and J-11D radar and network them with KJ-2000 or KJ-200 AWACS fleet ?

All modern fighter aircraft should be capable of network centric warfare. PLAAF has its own secure datalink to do so.

You will have to consult someone with greater technical expertise than me.
