No, it is
YOU who still do not understand.
You talk as if American pilots needs SEAD escorts in every mission. We do not. When we fight, at least for the Air Force side, we want to take out as many types of enemy forces as possible. If there is air defense and if we can fly SEAD escorts, we will fly with the entire strike package and attack everything. If the target is valuable enough to warrant mass destruction, we will fly with every possible form of attack at our disposal.
So what? That could simply mean intelligence was detailed enough that the Raffles can sneak by. We done that many times in the past.
Now it is definitely bullshit.
Whoever you talked to, either they do not know the basics of radar detection or they are outright lying.
The radar cross section value is a
DIRECT response of the combination of shaping, materials, aspect angle, and signal characteristics. We know that the RCS value directly changes with freq, so to cancel the incoming signal, you have to know its characteristics to generate the appropriate out of phase signal. Anything else, you are essentially guessing. If you guessed wrong and generate a countermeasure signal that even slightly deviate from the incoming signal, you gave yourself away.
What SPECTRA seems to do is calculate -- or guess -- the Raffle's RCS based upon analyzing the incoming signal. This is not the same thing as sampling the signal. You gave the hint as to how SPECTRA works back in post 5156 page 344 and you did not even know it.

Why does the Raffle need such rigorous RCS measurement whenever a new form of payload is added to the jet?
Because the RCS value will change. With each measurement, the new RCS value is added to SPECTRA's library. Not a threat library, but a separate library of its many RCS values based upon different measurements of many different configurations.
If a bomb is removed, SPECTRA will move to another calculated countermeasure signal. If a missile is removed, SPECTRA will move to another calculated countermeasure signal. And so on...
So from this perspective, SPECTRA does not need to sample any incoming signal. But if it encounters a threat signal whose characteristics does not exist, what then?
RCS measurement is active, not passive. The body is put under radar bombardment from all angles, at different freqs, and should be with different signal characteristics. With each round of measurement, SPECTRA calculate the Raffle's various RCS values based upon
WHAT DASSAULT KNOWS of those signals. Not what could be in combat.
Air defense radar signals are well known in their signal characteristics. You have a set of freqs for long distance search, a set for tracking targets, and a set for high focus for missile solutions. So yes, Dassault can test the Raffle with these known factors and SPECTRA can certainly calculate the necessary countermeasure signals. AWACS signals falls under the same rules so their signal characteristics are also known.
But not against the F-22 and F-35, buddy. AESA systems can generate signal characteristics that are absolutely unknown to Dassault just on the freq agility factor, let alone much more complex factors like pulse variables.
But am beginning to suspect that the real bullshitter is
YOU when you did not realize how the system works from your own words.
Looks like I understand SPECTRA better than you do.
