This should finally put an end to any doubt as to whether China has AESA radar for fighters.
Here's the slightly larger version ...
well, that's clearly an electronically scanning radar based on the shaping. The only thing is that it might be a PESA radar. Now, I'm personally off the belief that it is AESA, but I can't say from this far out that it is AESA radar for sure.
Given that China has done very little research in PESA I think it is safe to assume that if the radar in question is an electronically scanned radar, it is most likely an AESA.
