crouching slows down the pulse on radar. If you're not moving you are off the radar for about 3 sec, less time if crouch walking so it gives you a small window to try and make a play. If you duck when someone is on the outside range of the radar they will naturally think you are going away from them and start to charge towards you. Crouching does not work if you are in close range (center of the radar) it will just continually pulse.

TLdr: crouching keeps you off the radar for a small amount of time. less if crouch walking.

Hmm, I wonder if that's to discourage camping, because they could have just kept it so that not moving keeps you off the radar entirely.
