Do you know who is this fellow?
Even in detail, you have no idea who is him.
and, do you get who is this?
In most case, identification is based on a good enough database containing the unique properties of the objects.
come back to your case,
We don't know who they are, at least we can...
1) C-5 and B-747 are totally different flying objects and they have as different radar signature as your fingerprint---- you have to admit it.
2) Even the radar signature are similar and difficult to identify, we still have great chance to do it. e.g., route, flight timing, altitude, flying in...
F-22
Base on the subject's distance, RCS, Speed, it will not be so difficult to identify they are F-22.
Most difficult part is the process of making the database for all the possible objects.
Remember: different object always feeds different signal to radar, that's the identity.
If it is...

Dassault Rafale, tender | News & Discussions is crawling to thread 2 @page 86 and looks still young.
Who will spend years and years to talk terms and conditions for just want to buy something if he is not from lovely south Asia?
Talk, talk, talk, delay, delay, delay.
There always have enormous...
To sit down and think why we need to develop 15th gen from 5th if they are same as you thought of?
====
There always have new challenge to hide the aircraft or any other things from radar.
We need to change a lot of things to cheat the new developed radar working in different band, mechanism...
It's really laughable and shameful of somebody to act as an aircraft-stealth expert on an internet forum.
In that case, either he/she did not have to sign a CA since he/she works as an barber in the company, or he/she is a retired taxi driver only.
============
The gaps come form last...
You make the science racialism and it makes your opinion less valuable.
Just imagine what if we exchange the air intake between F-22 and J-20.
We are expected to be flooded by milky way of stuffs to explain why and how the gaps increase tons of RCS.
But it is okay on F-22 raptor. Yummy!
Aren't h-tails the same?
Extra RCS is from the "must" you imagined or the "must" from your primary school education?
F-22 has two huge H-tails for they are too close to the main wings even overlapped.
J-20 has smaller canards for they are far from main wings.
Their size is decided by...
Oops, you must have forgot to brush your teeth after eating rotted food.
Why wings + h-tail decrease RCS while carnards+wings increase?
Stealth is based on science facts, not your bare eyesight and small volume brain imagination.
Forget your F-22, it's stopped production and waiting for dying...
That is not true.
We should think in this way:
Front: F-22 has two huge wings, J-20 has two small wings (canards)
Buttock: F-22 has two horizontal tail and J-20 doesn't have.
