I think you’re making it clearer and clearer that you yourself aren’t certain what it is you’re discussing.
Regardless, the AAM-4B seeker has 1,516 slots that I can identify:
What you are implying with the brick type T/R module is that each module itself has a ton of individual T/R modules correlated to each antenna element or it isn’t AESA and is in fact PESA like so:
@WreckingAres283 Looking further into why that AAM-4B seeker has a horn it seems to align more closely with a “Compact Dual-Polarized Continuous Transverse Stub Array with Two-Dimension Beam Scanning” as outlined in the linked document.
Could be an early test of electronic beam steering rather than an official seeker for the missile.
PESA and AESA only differs in that T/R modules is singular in PESA and multiple in AESA. AESA radars however still has T/R modules ‘packed’ into brick modules enabling separate control but allows for standardised production and can be used in various systems with different diameter and size. Also nothing forbids a T/R module in an AESA radar to have multiple antennas, as long as the separate T/R modules are still able to be controlled separately.
That is nonsense
That isn’t always true
What you said isn’t making sense.
Antenna modules as long as able to be controlled separately is AESA, and if controlled by uniformly is PESA. The line is blurred however for AESA with multiple antenna attached to same T/R or PESA with more than 1 T/R module.
So with the PL-15, which you have admitted shows no T/R modules, you are saying it can be PESA or AESA? How do you know for certain? That is all I am asking.
I am not the one who concluded that this is AESA from this picture. My defence is based on the fact that 1. having holes doesn’t mean it is slot planar array and 2. This is the first time we have seen any part of the seeker, but as this picture showed there are more to it than just this bit, cause this doesn’t even confirm it to being a PL15.
This is what confirms it, I look forward to seeing more of it to shed some light on the issue, however I can not confirm that it is AESA, but that is not excluded from the possibility and as far as public information shows the PL15 did have an AESA seeker.
As for PESA, my suggestion would be that it requires too much power to have 200km range, assuming PL15E and PL15 uses same seeker.
(MiG31 for example)
Okay, so the fact that it matches a slotted waveguide antenna design perfectly should be counter to this. Glad we cleared up the confusion.
Which you can not confirm either. The structure u mentioned shares little similarity and also is completely based on ur assumptions and no evidence.
it’s a test unit, which is much larger than real missile
Source ?
It says Ka band experimental device for AAM-4 and SSM-1
and the lock(in colored image) under the device suggests it’s quite a large device.
You know they make small locks right?
I know it was a prototype, but nothing suggests its larger than the actual head.
the lock and the metal name plate on side, suggests it’s a really large device.
They make small metal name plates too
I guess you are joking. this is just a normal nameplate you can see in most devices
No, they make many different sizes of name plates. It doesn’t really mean anything for the test things size
nameplate is used for read, no need to make it small, same for the lock.
it’s a device for experiments, not a delicate miniature
I believe this is not the antenna. it’s just a back plate, the “units” are just copper contacts used to weld the units. same part of the PL-15 antenna’s remain
