Yes.If IWB doors opens, it can be seen on Radar right.
It even isn't an AI task.The “TV Expert” said, the AI on KAAN knows, where the radar beams come from (angle) and turn the plane to become less visible. Is that correct?
All modern fighter jets do know when and where they get "marked" with a radar on the merit of their advanced RWR systems.
Rafale's RWR can guide a bomb to said radar's location(that's how they got one of our Hawk batteries in Libya AFAIK.) and EF2K's RWR can provide guidance data to plane's own Fox-2's in order to intercept A2A missiles coming for the jet.
Chinese J-20's can also adjust the angle of its canard's to maintain radar stealth, allegedly.
For air-to-ground scenarios, you need to turn the plane upside down to make the plane "turn his back to the radar beams." you ain't dropping bombs in that scenario.What’s happen, when the plane turn his ‘back’ to the radar beams, during he opens his IWB doors ? Can the radar detect the open doors?
In air-to-air scenarios, it doesn't matter that much anyway.
