How does it work?
The Rocky Mountain Radar scramblers are full-featured
radar and laser scramblers combining active laser and
passive radar scrambling capabilities.
The radar scrambling circuit mixes Pseudo Random
Digital Noise Generator (PRDNS) 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
White Noise confuse the computer in the radar gun so it
does not display any speed. This effect duplicates the
normal operation that the officer often sees.
Since it is normal to occasionally lose the target speed,
the officer is not suspicious. Reasonable care should be
used as flagrant violators could still be caught with an
estimated speed.
The laser scrambling circuit transmits a series of pulses
at the same wavelength used by the police laser guns
(Lidar), which are electronically timed at about 100 feet
apart. When the pulses pass through the windshield they
will lose up to 50% of their power. The power output is
6 to 10 times that needed to trigger the detector in the
laser gun. Lidar sends out laser pulses and measures
how long it takes to hit your car and come back. From
the speed of light it can determine your range. It sends
out several more pulses and calculates your speed from
the change in distance over time. The Rocky Mountain
Radar scramblers only allow the Lidar to see up to 100
feet so it is unable to calculate your speed.
