Radar units require multiple returns AT THE SAME SPEED in order for it to display. Mind you this happens quickly but nonetheless, many identical returns. This is in the violators favor. Braking very hard (hopefully no one is close behind you) will most likely not allow the radar unit to display the target speed because the speed is changing so rapidly. Also returns from much bigger vehicles will dominate the returns that the radar unit receives. The audio portion of the return can be heard for both vehicles, lower pitch for slower vehicles, higher pitch for faster vehicles. Because the dominant vehicle gives a stronger return (doppler) and the unit can acquire the multiples it needs for it's logic, the display will indicate the dominant vehicle along with the audio returns for both.
Many people believe that a radar display is primary information used in traffic courts. This is a misnomer. The officers observation of your speed is primary, and supported with radar, laser or vascar. Convictions have been supported by observations only.
