SPEED MONITORING TECHNOLOGIES

Radar Facts

A radar gun operates by transmitting radio waves at certain
frequencies which reflect off objects and are then picked up
by the radar gun's receiving section. When a radar beam
reflects off a moving target, a measurable frequency shift
occurs. The radar unit converts this shift into miles per hour to
determine your vehicle's speed.
Currently, the FCC (Federal Communications Commission)
permits operation of traffic radar guns at X Band (10.500 -
10.550 GHz), K Band (24.050 - 24.250 GHz), and Ka Band
(33.400 - 36.000 GHz).

Laser Facts

It's well documented that many radar guns cannot reliably
provide the speed of a targeted vehicle that is traveling in a
group of vehicles. In contrast, a laser gun can target a specif-
ic vehicle out of a line of traffic and determine its speed.
The advantage of laser over radar in terms of target
identification is the result of the laser gun's narrow beam. A
radar transmission can cover more than a four-lane highway
at a distance of 1,000 feet, compared with a laser transmis-
sion which covers about 3 feet at the same distance.
For best protection, keep these points in mind:
• Your vehicle's license plate or headlights are the laser gun's
primary targets.
• Do not follow closely behind any vehicle you cannot see through. If you
can't see past a vehicle ahead of you, chances are your detector won't
either.
• The receiving range of your laser detector will not be the same as a radar
detector. Laser guns are most often used at short range.
Whistler Laser/Radar detectors receive all current laser guns which
operate at a laser wavelength of 905 +/- 10mm.
