China - J-11 Modernization program

Needless to. I know that it lowers RCS.

And I have shown you a long time ago how a SPECTRA-like method has weaknesses that can be exploited.

Your saying the DSI reduces RCS? I say DSI has a different function. DSI can be angled to reduce RCS but a normal DSI like the one on the JF-17 won't do much for the RCS. I hope your not making claims at knowing how to reduce RCS, if so i recommend you work for lockhead.

Spectra is active. It attacks a radar that has locked on by bombarding the target with the same radar waves in order loose the lock. Theoretically it should be effective against missiles with active seekers.

Intakes like that eliminate the need of ramps, which increase RCS, needless of angling.

SPECTRA is really a stealthy form of jamming.

Okay...at this point I don't want to continue this discussion. I recommend to you that you read up more on DSI and stealth on avationkeypublishing forum. it could enlighten you. If what you are saying is true, than the F-22 will have a higher RCS than the J-20 and F-35.
BTW what exactly is "stealthy form of jamming"?
AFAIK Spectra is jamming.

Wrong.

SPECTRA is really a stealthy form of jamming.

And more wrong.

Not quite. It is similar to jamming but with a different purpose and it is best against third and second tier air forces. The SPECTRA system works basically upon the techniques of analyzing incoming radar signals and attempt to create what it calculate to be the characteristics of reflected signals.

DRFM is the foundation of the SPECTRA system.
