Re: OT Shields really exist?
Radar can be interfered with by absorption or by reflection. Reflecting the radar signal off in a specific direction away from the receiver, instead of directly back at it where it can be received. Or by a form of reflection called scattering, which is reflecting parts of the radar beam in many different directions, so that the receiver cannot get a consistant return.
That is why the F-117 has all those wierd angles. If it was all about absorption, they would simply make a regular aircraft and paint it with radar absorbing paint. Which they do sometimes and it helps, but it's not as effective as a stealth aircraft with both principles in play.
