That’s the wrong analogy. A better analogy would be if I sent you a .jpg image that had an imbedded code, your mirroring of the image wouldn’t necessarily reproduce the imbedded code hidden in that image. Think of it as kind of an electronic water mark.

But how would you do that exactly with a radar wave?

The altered signal won’t be coded. This makes the task of picking out the correct return signifcantly easier,

Why couldn’t the ECM system replicate the coded signal?

not to mention that due to the rapid change in freqs, a second return of the wrong freq will also be a huge indicator.

The ECM system will stop emiting the signal almost instantly after the radar stops emting it, so the radar may just be fooled into thinking that the plane is just farther than it is if the signal takes longer to come back?

That’s not correct. If you send a coded noise-level signal the receiver will not know if it’s a noise or radar’s signal. However a radar that sends that coded noise-level signal knows the code and when it receives specific coded ‘noise’ it will amplify it and recognize it as a return signal.

the signal can’t be a “noise level” signal during its all path. So will it be a noise level signal at the time it reaches target (then it means you must already know the target range to emit accordingly?), which means that by the time the signal comes back to you it’s way below noise level, so how can you pick it up? Or does it mean it should reach you at around noise level? Making it higher level when it’s on the target?

You’re right. It won’t have that capability for another 4 months.:rolleyes:
…
The F-22 can receive Link-16 updates.

Why are they adding those capabilities to the F22? I’d think it would be more important to add AIM9X and a HMS, and conformal aesa arrays for instance, if you consider the numbers of F22, there won’t be enough numbers to do both AtoA and AtoG weapons.

Does it mean the USAF think the F35 won’t cut it in the SEAD role?

Datalinks do ring a bell?

No what is it?

Never said that, and I didn’t bring the 1vs1 fight to the table, it was a rhetorical argument with wrightwing at first.

But if nobody uses their radars, I don’t see what the point of a stealth fighter is. I see it for a bomber or attack aircraft though.

Now I can understand the lack of F-22 orders, expense and unwillingness to export, but what explains the lack of Rafale orders????
Maybe the fact that DACT is only used to validate existing tactics and for training against unfamiliat tactics ( what do the D and T stand for in DACT ??), NOT determining the ultimate combat ability of an aircraft.

How about politics and bribes?

If Rafale wins in Brazil, it will also be a purely political decision. Same with the UAE to a lesser extent.
