it's basically a description of what JY-27A is. I don't think it mentioned AESA in there anywhere. Just VHF phased array radar.

Ah.... No.

This must have been one of your 'snap' replies, seeing that you obviously hadn't bothered to read my post.

Since you are in such a hurry, let me save you some time by pointing out the relevant portions from my original post:

"该雷达采用固态有源T/R组件和两维DBF技术,大大提高了系统任务可靠性和时间资源调度的灵活性。", which translates as "the radar uses solid-state active T/R module and two-dimensional DBF technology, greatly improving the reliability and flexibility of the system task time resource scheduling."

Solid state active (有源) T/R modules, check; DBF (i.e. digital beam forming), check; VHF, check.

So AESA VHF radar this is, isn't it?

Now may I suggest that you read my post first before replying. Otherwise, you are simply wasting my time and yours.

Cheers.

Looks like you have some serious anger issues against me that you should sort out. I assume this is due to a past time where I moderated and/or commented on your posting. Please respect the role that moderators play on this forum. Now if it isn't due to grievances from my past moderation, please be more respectful in tone that you would use to another member on this forum.

I am not an expert on stealth / anti stealth but I think the report linked below is an interesting read.

Perhaps it was addressed elsewhere but I did not find it so let me ask it here: leaving aside other matters (his views / agenda etc.) when it comes to purely technical matters are the works of Dr Kopp regarding Chinese aircraft, weapons, radars and so on a good source of information?

He is an expert on Russian systems, but not so much regarding Chinese equipment . One of the reasons for that is, of course, because China remains secretive on military maters, while Russians after the dissolution of USSR are aggressively seeking customers for almost anything .

I would go further and say that no one in public is an expert on Chinese weapons systems. Anyone who actually is is probably looking at classified data.

No, that is Carlo Kopp, and he is only an expert at taking Russian brochure statements at face value and extrapolating wildly from those statements by saying how the F-35 is somehow completely ineffective and that anything short of the F-22 is completely inferior to Flankers. Carlo Kokk is a tool.

To put it more mildly the guy is using open sources to write his presentations. Or putting it another way when reading through his materials keep in mind that these are compilations of OS – nothing more.

At first I wanted to avoid this but guess it is not possible – he is arguably working with or for some lobbyists who want to sell Australia (want Au to buy – amounts to the same) the Raptor. For this reason the analysis & conclusions are bias.

Question: Radar early in WWII often used antennae at the wing tips, I understand because of the long wavelengths used at the time. Why doesn't airborne anti-stealth radar use a similar configuration?

Well, supposed L-band radar on PAKFA could be just that - radar placed in the wing . Of course, it very hard to fit large antenna into something that should go over 2 Mach . We shall see ...

Adolf Busemann invented a supersonic biplane. With antenna elements in the wing outer panels of both top and bottom wing you should be able to achieve an effective antenna for "long" wavelength radar.
I would think a subsonic biplane carrier base AWACS aircraft might well be superior to a conventional radar aircraft with a saucer above its fuselage.
