It is very unlikely that any radar gun could be built that times the
arrival time of a reflected pulse.  Much more likely is a system based
on doppler.  See any graduate level text on communications theory (for 
example Gagliardi) or radar for more information.

Spoofing radar is very common in the defense community.  Contact your
friends at TRW or any other of the military/electronice industry for
more information.  (I can just conjecture what they do.)
