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.
