What is the actual distance that a radar can pick up speed with a clear line of sight. The reason I ask is that I was thinking yesterday that the return radar (after hitting object) is weaker so how weak can the signal be before the unit doesn't pick it back up.
Yesterday I got hit with Ka on a straight 2 mile stretch. My STI went off forever, until I passed the car and it quickly stopped, so it doesnt pick up the return signal nearly as well as the original. THat is what made me start thinking about this
