I suspect this was covered already, and I'm no radar expert, but...

I have seen for sale at a place in Chicago (Warshawski's "everything
automotive"), a radar gun. This looks to be the sort one sees on TV when
there is a demonstration of a pitcher's fastball or some such thing.
However, if such a thing were to use the same frequency as police radar
(which it probably does not, but bear with be)
What would happen if one were to mount this on the hood of ones car?
I mean, as I understand it, the police sensor is expecting to recieve a
signal shifted by amount X, from getting bounced 180 degrees. Wouldn't
the same device on my car register X/2 : in other words, if I was doing
100 MPH, it would read 50, wouldn't it? 
There are a few subtleties, like the fact that a radar gun presumably
emits pulses and you would have to match timing.

It would seem that everyone is looking at it from a "stealth" point of
view. However, we do not wish to be invisible, we simply wish to seem like
we are going slower than we are.

So, is my theory full of shit, or what?
