You can go here...I see.
so is J-20 multi-role or just air superiority?
I wonder how the canards effect stealth.
Fundamentals of Stealth Design & Concepts of RCS Reduction
...And read about the foundation of designing a radar low observable body.
But I will sum it up for you:
- Nothing is invisible in radar detection. Radar sees all.
- Everything on a complex body is a 'radiator' or 'emitter' of radiation, whether that radiation of reflected or powered transmission.
- Therefore, the rules for designing a radar low observable body are:
1) Control the quantity of radiators.
2) Control the array of radiators.
3) Control the modes of radiation.
The J-20's canards made the aircraft immediately suspect under those rules. Nevertheless, to be fair, in the absence of hard measurement data, we should refrain from making definitive judgements. China will never release those measurement data,, just as the US will never release the F-22's version.
