Mount 4 or so corner reflectors on a rotating frame such as a plastic bicycle tire. Coat the back of the reflector with resistive foam to dissipate the radar energy. Make the corner reflector large enough RCS (Radar Cross Section) wise to be much brighter than your car. Turn the reflectors at a constant rate of something like 120 RPM. And wa-la your car's dominate doppler shift will be ~ 10 mph less than you are actually going. That is assumming you can figure out which way to turn the reflectors ;) The apparent speed of the reflectors will have a sinusoidal modulation to it from going around in circles. This may prevent the radar from getting a good lock on the doppler shift and lock in on the steady doppler shift from the car even though it is dimmer RCS wise. If this is so then you put your corner reflectors on a flat belt and rotate them like a belt sander. I would hate to get caught with something like this on the top of my car. :^) -- // Mark M.
