How does the RMR-C302 and Phantom III work?
The RMR-C302, Phantom III detector-jammer is a full featured radar and laser detector combined with passive radar jamming and active laser jamming capabilities. The radar detector is a dual conversion scanning super heterodyne receiver with separate alarms for each of the radar bands, dark mode, mute and city/highway select. It detects front and rear laser and radar. The radar jamming circuit mixes a Doppler FM chirp with the incoming police radar signal and reflects it back to the radar gun. The computer in the radar gun must receive eight identical, consecutive readings before it will display your speed. All the different speeds contained in the FM chirp confuse the computer in the radar gun so it does not display any speed. This effect duplicates the normal operation that the officer usually sees. Since it is normal to occasionally lose the target speed, the officer is not suspicious. Reasonable care should used as flagrant violators could still be caught visually with an estimated
