In article <567@moncol.UUCP> ben@moncol.UUCP (Bennett
Broder), in response to a question of mine, treats us to a
small excerpt from a grade-school physics class, explaining
how radar guns use the Doppler effect to determine speed.
Unfortunately, that wasn't the question.

I'll ask it again: Is the transmission from a radar gun modulated
in any way so that the gun can distinguish the signal it
sent out from the signal coming back in IN THE SAME BAND?
Examples of extraneous noise are: door openers, other police
radar guns in the vicinity, radar jammers, and probably the
3K background.
