Chinese Air-To-Air missiles, History, Performance & Discussion

Dual use technology I guess. This stuff’s gonna end up in someone’s microwave oven someday!

Why Ku band though… I’m not too familiar with this stuff, but isn’t the power to frequency shift for each TR module, that makes AESA good and hard to detect?

As I know, one radar can only have one band, you can make a dual band AESA, because it’s formed by units, but it’s just make them into 2 smaller radar.
this kind of design often seen on ships and AWACS, 2 different band radar back to back or stand together, and share same backend, usually one for searching and one for tracing.
but in missiles seeker, a limited environment, it means performance loss.

I remember advanced AESA radar has it’s way of making it hard to detect, usually against old type RWR, by managing its tracking pattern

A few more.

Spoiler



the picture of the wnb7068h T/R units could from LY-80, this matches the time, delivered in 2016
the others still match the pl-15 seek image

That’s PL-12AE lol.

Do u have the full pic? What was it hanged under.

Speaking of which, maybe someone can write a PL-12A suggestion over the suggestion board so we can have something to fill the gap between PL-12 and PL-15/PL-15E.

That wasn’t the backplate though, the front has square style antenna and the modules are on the back, This missile has quite a substantial number of antenna–but about half of what was shown on the AAM-4B test subject it seems.

If this is indeed the same wreckage and scrap, that is an AESA radar.

That thing showed according to u nearly as many as an F35 lol.

Yes but count is not the only factor, there is also size and power among a myriad of other things.

I’m sure it’s a quite large one. a test bed for aesa seeker not just AAM-4B.
Aesa unit has its size and performance limit, that’s why the number of units is often used as performance values(other things influences too, but units sets mechanical limits)
it’s a fixed aesa in a 8 inch missile, I believe it’s the biggest aesa that can fit in

Based on what the plate with writing? I’ve seen plates with writing like that with the same square mm as a penny on things like turbos let alone advanced AESA seekers.

I doubt it is the biggest, I think there were a great many other factors but certainly it is more than sufficient with over 400 T/R units for basic air to air missile duties. Comparing it to what we know about AAM-4B, however, suggests it is still behind the “West” as far as fitting AESA seekers in a missile goes. It would be pure conjecture, but I assume things like the AIM-260 will simply beat it outright on paper.

That is only on paper though, and of course, it has still had a wildly successful debut against the Rafale.

should be less, same for the real AAM-4B seeker.
you need the size of AIM-54 to hold 400 units.
most calculations are around 300 units, already very strong for a missile seeker, needs exaggerated battery and heat dissipation for a missile.
I think your count of the AAM-4B seeker test is also incorrect, considering this↓

and area of the radar cowling is often used to estimate the number of radar units

it’s a test unit, not real seeker not for install, and the name plate is on pedestal, no need to be small.

How do you figure my count is wrong? I counted the antenna squares, obviously from the sources I posted before these are generally each attached to a T/R module individually. Can you show that the calculations and how they figure 300 units?

because they are not t/r units, you can check every known aesa seeker or radar, count their units and area, do some math, you will find it impossible to fit so many units into a missile

U know how big the area is right? (203/2)^2 *pi. Even if not accounting the fact that the antenna does not occupy the entire missile cross section, the antennas are 20 mm^2 , nvm if we account for the areas not included, 4mm by 4mm t/r modules?

Right, which brings me back to my point, how do you know it is AESA?
Is it because it says T/R module on the side of a piece of wreckage? What is the use of so many separate antenna pads? Did you even read any of the source material I shared earlier?

In fact, yes. Although not confirmed.


It does say T/R module doesn’t it.

Yes, but each of the squares is an antenna. What you are suggesting is that multiple squares share a T/R module, which if I am understanding these radars correctly, is somewhat silly.

They don’t share a T/R module, but rather are packed into 1 T/R module pack of IDK how many, likely 12.
Also I think @NCC105 meant AAM4B thing and not PL15.
