Tekhomirov NIIP AESA radar unveiled for PAK-FA

Greetings from MAKS

here is brief translation, just basics:
it is for 5th and next generation of aircraft (they probably mean 6th by it), diameter 2 meters, thickness 0,5 meters, 10 mio USD a piece, it is AESA, first demonstration unit, technical characteristics still secret, unit should be shown on MAKS, it is functioning unit. No wooden mock up, but real working unit (repeated). No words about range. Contract on demonstration phase to be signed. Its predecessor Irbis radar mentioned. AESA should be able to distribute information (probably fighter-fighter, or with ground control??? doesn´t say). Technologies icorporated understood well enough to enable serial production. I didn´t completely understand talk about processing reflected signal?? (starting at 2:00). Can anybody help?

I have not seen it myself, but it is really good show. Su-35 and 30s were incredible.

Hello Stephen,

Just a minor correction, it is Tikhomirov and not Tekhomirov. :)

Hi Martin - nice job capturing the pertinet details (although I believe they mention the antenna has a 1m diameter, not 2m ;)

Starting about 2:00 this is what I think is being said: the gentleman is describing the anechoic facility for testing the antenna - he shows the equipment including the "APU" - or antenna turning (pointing) assembly. When he talks about the reflected signal he is describing that at the back is located the "collimator mirror" which allows them to produce a flat field (wavefront). The reporter then explains that this allows the antenna to receive the "reflected" signal as if the antenna was at a distance (radius) of 100km from the target.

Great googly moogly! That is a big AESA antenna.

Not sure if this is an attempt to make up for inferior technology on the chips, but it appears to be at least twice the area of the F-15's radar.

It should do a pretty good job, even if the tech is not as good, because antenna size tends to make up for a lot of shortcomings.

At 2:00 they're showing a testing chamber, the geometry of the plates allows to simulate working at a long range (hundreds of km, they say)

In a nutshell, after 2:00 they are showing the facility they use for testing and the specialized "mirror" apparatus used for simulating radar reflections at approx. 100km.

TWO meters in diameter?! No way, I'd believe one or a bit over one but not two meters. I've heard that some folks have already counted the modules at 1,500 which puts it in the APG-77 class as expected.
