        I’m sure it’s been explained here many-a-time, but whatever…

        A radar gun’s main component is a ‘horn’ (laymans: a cone shaped thing
that has sensors in it to detect radar waves). Now this gun is at the back
(in other words, the side that doesn’t have the lights on it) and it’s
pointing forward. Now the way the detector senses waves is by the waves
bouncing into the horn. (side note: Radar waves are like superballs; they
bounce off of anything and they go everywhere.. that’s why you pick them up a
mile down the road.)   Since the horn is facing the front, the only way your
detector can sense waves from behind is by the radar bouncing off of something
like a bridge, tree, duck, etc. and hitting you from the front..

Whatever.. I think you might get the idea.
