This is a bad source
So how do you think the F.3 RWR was able to identity an R-27 launch without knowing the guidance frequencies?
RWR measures in a wide range
Yes it captures in a wide range but to ID specific systems it needs specific frequencies. Otherwise it would just alert for I-Band transmissions. But it doesn’t, it can specifically ID the weapon system.
I doubt it very much, given that the data given for P-27 in this source is absolutely not correct
The kinematics of it absolutely are guesses based on intelligence data. But the guidance frequencies are taken from readings of launches.

If that’s not the case then we can pretty much throw out threat ID for all RWR where in a country doesn’t operate the weapon system directly.
We need to look at the fact that an export missile was used there.Not the original one

So here we go again, can you prove the seekers of the export R-27’s operate in different frequencies to the originals?

Yeah ±55kts. F15 is 48kts lowest option for both hprf and mprf
I’m not going to disclose this information to you.

Okay that’s fine.

Nope. That 10-20GHz figure is just a brochure figure. 9-10 GHz must be towarda it. Why? Because receivers work at certain frequencies. The have a certain resonant wavelength where the impedance is low, several dB lower(in the order of 10s and remember that -3dB is 50% loss)
This is a physical characteristic, not digital/electronic where you can just say " I’ll now put the frequency at x and later at y and I’ll still have the same return strength". It doesn’t work like that.
Look at a simple dipole antenna. The resonant frequency is at half wavelength. If you change the incoming signal frequency, the signal recovered will be much of much lower strength. Claiming 10-20GHz is just not right, the wavelength at 20GHz is 50% of 10GHz. Soviets went for radio correction as the missile didn’t see the target(poor manufacturing, electronics etc) at longer ranges unlike sparrows (20 - 40 nautical miles for small targets), I’m pretty sure they wouldn’t allow further acquiring range loses.
You’ll not change the receiver antenna size everytime. Plus that information not only comes from SIGINT, but information from spies aswell like the one the guy in the other r27 thread has been yapping around. For what is worth, that document is accurate. I tried to find , indepenedently from it the frequency of the mig 31s radar knowing the diameter and amount of elements, assuming a half wavelength separation between the radiating elements, you can have an idea of the frequecy it operates( I was 0.5GHz if I remember correctly).

Its a shame we couldn’t have found this out like… a year ago when any of these potential inaccuracies would’ve made a difference in the SARH meta Lol
Maybe we’ll have to try to get a head start on the R-77s when they’re added instead of when R-77-1 comes out :P

and the roll limit report.
Yeah, even if it gets reported on the while its on the dev it’ll go ignored like my previous reports. And then just wait several months till for literally a fix that requires a single value change. Even flight performance issues get dealt/ fixed faster and I’m pretty sure they require far far far more complex testing to identify the issue and fixing it without performance drops in other areas.

And the classic to make stuff artificially overperform but ofc the phoenix cannot reconnect even if you relock…

I should bug report the Phoenix SARH mode not having datalink reconnect lol
