Re: Many have said China has catched up or even surpassed Russia in electronic tech b

more info on russian AESA program from australian airpower com.
russian trying to interest the PLAAF to purchased zhuk-MSE AESA radar to retrofit existing su-27/J-11 fleet.
to date there are no response from ther Chinese,it is likely that Chinese AESA may already been undergoing test flight test.according to brief article from wmf, claim that detection range (max.)for J-10B radar is 200km,there are no mention whether this radar is PESA or AESA,but it may be pointed at AESA.
NORA/ RBE-2- max. range 195km. APG-80 (F-16)-200 km

There's a video on state television where a PLA spokeswoman states that a J-10 has been equipped with some sort of electronically scanned radar (which I assume would be AESA.) Obviously still in the testing stage.

The one on the J-10B is obviously some kind of electronically scanned radar. Radome space is too small for a radar dish to pivot, and the firewall, meaning the backwall, is canted, which means the radar is most likely to be fixed in a canted position.

Real innovation in radars is in the software.

when I say surveillance, I was talking about AWACS and you bring up a VHF radar and solid state phased array radar? And is there any support to them being AESA? I have never heard of VHF band radar being AESA.

Its off-course from Carlo Kopp, but you can get some details:

More from Copp:

He has allot of JSF bashing but, you can get some details

Well the , , also have rather small noses....

But, that being said,

You right about its position. Its canted. Question is, whether its AESA or not. ,

PS:

Skywatcher watcher was right. There was a video where the interviewee claimed the J-10A had an ESA.....

Re: Many have said China has catched up or even surpassed Russia in electronic tech b

I don't know if the ESA is specific to all J-10A models, or just some trial run.

My guess is that it would be AESA, mainly because we haven't seen too much Chinese work on PESA compared to AESA.

Well I think the main point is that it looks noticeably smaller then the J10A's nose.

There is no good reason to make the nose smaller unless you expect to get at least similar radar performance out of it, and together with the canted nose strongly suggest ESA.

yeah, that sounds about right. Kopp has never been ashamed of being a little loose with technical details.

Re: Many have said China has catched up or even surpassed Russia in electronic tech b

I did a google search on "China 12Ghz 10Ghz T/R Module RF Highpower"

no specific products come up. Do they make them for commercial products too?

OK, maybe Russia are not quite there yet. but at least it earning kudos for demonstrate working or semi working prototypes in different confiugrations, points for being creative. AESAs, PESA Bars, and Planars.

I only see Planars with China, that's not very creative.

Don't let the fanbois mouthing defense brochures they read fool you, planars are actually very efficient antennas.
