Typical modern police speed “radar” operate at 35 ghz and have a 3 or 4 inch aperture. That gives them a beam width of about 12 inches. That’s about the width from your thumb to the tip of your index finger at arms legth if you put them as far aparts as possible. While these devices are call radar (RAdio Distance And Ranging) they really only measure Doppler. Furthermore. they always pick the highest value to report. And since its computerized, its your against the Borg.
