Your “research” consists of looking things up in Wikipedia? Perhaps you should leave threads like this to people who know something about the subject.
Look is that a yes or a no. The Wiki talked about photos from various airshows. And I went and looked at them.
Why are you doing this? You know perfectly well those aircraft have flown in Syria.
I’ll help you out. Here is what you need to learn about the on board systems. Learn the difference between the gain from a parabolic dish and an electronically scanned array. You’re helpless if you are not up to speed on at least that.
Track while scan dates back to F-16 days. There evolved to be a total target number that could be internally, electronically (meaning in the computer) tracked, while breaking lock on a target and rescanning the sky. The SU57 radar of course does this and the claim is 60 targets velocity vectors are stored while the phase changes on the antenna elements take place to do the scan.
This is very sophisticated stuff that is not new. Of course the SU57 will have this on its Belka radar. F-16 was built by Westinghouse. F35 by Northrop.
Go look for analyses showing how the F-35 suite is superior. This will be so in many instances, though not all. And the point will be after you actually learn these things . . . it would not even be an analysis to be performed if the pulse repetition frequency of the SU57 were not already measured in Syria.
Which means, btw, that it already flies.
