It was used during WW2... It can be cool fooling the radar using Chaff. It should be available on some heavy bombers like: B-17, B-29, B-24, Ju-88 etc.
if it worked properly, the dar would show nothing but a big red blob...do that at 20k with a single plane just inside the dar circle of a base then after a bunch of cons up from the base to intercept, sneak an noe mishun from another direction. that is until people figure out how what's going on....
I don't think it would be good for the game. Too much avoiding combat as it is.
Or perhaps the use of chaff would promote combat. I can see where the bomber pilot might feel he has a better chance of surviving/completing mission if he can spoof the radar as he's inbound.
Do not run.Face your opponent with all you have.If you die you have something to learn.
