How does the Black Widow work?
The Black Widow is a 360 degree active laser and passive radar jammer that you attach to the front and rear of the outside of your vehicle. 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 speed. The Black Widow also transmits a series of invisible light pulses at the same wavelength used by the police laser guns ( Lidar ) which are electronically timed at about 100 feet apart. Lidar sends out laser pulses and measu
