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 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 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 four to
eight 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.
