stealth is not just about the coating on the airplane or the unclean lines that bounce back radarpulses with a delay !

behind each stealtplane operating the strategic way are 4 to 5 other airplanes involved !

aerial refueling,countering radar pulses,back-up,rescue and the "foxes".

it is the mix of this all that operates under the name STEALTH.

Though it is true that a large part of the radar being emitted by a radar station is absorbed by the aircraft, there is still a lot of radar that is bounced off, mostly in different directions. Assuming that this is true, why not have radar stations work in tandem with each other, one acting as a relay and other radar stations acting as reception stations. The stray radar emissions bounced off the stealth aircraft would be detected by these reception stations and if compiled at real-time, would give a return on the stealth aircraft. Albeit this system would require multiple radar stations, money, and the synchronization of all the stations to a very precise degree, would it not be an effective and reliable way to detect aircraft, eh?

It would be very difficult.

Since the radar could be deflected all over, how do you know where to station the center? Also, what if it was deflected at such an angle that only airborn statinos could pick it up? I think it'd be a lost cause to try, but two stations could pick up a little bit extra...maybe.

do not forget that any magnetic field that you produce can have (uncontrollable) sideeffects and that these effects can turn to you the bad way !
it can arrange hick ups or malfunctions of other electroncal stuff.

i have read some stories too that the usaf lost radocontrolled stuff due to... the craft picking up radiosignals that came from other public devices !!

so if one intends to link all radarstations to become one big electronicall unit (like they do with linking radiotelescopes to search for radiosignals from space)...
there could be some unforseen sideeffects having impact
on other of your weaponsystems/airplanes/rockets/...
