A radar detector, sometimes called a
fuzz buster, is an electronic device used by
motorists to determine if their speed is being
monitored by a radar unit. To do so, police bounce a
radio wave off of a moving vehicle with a radar gun
that determines the vehicle's speed by the
Doppler-effect-moderated change in the wave's
frequency. Most of today's radar detectors detect
signals across a variety of wavelength bands
usually X, K and Ka (as well as Ku,
in Europe, also recently approved for use in the
U.S). These devices should not be confused with ones
that use GPS technology and a Point of Interest
database to warn a driver who is approaching a speed
camera location. Newer speed detection devices use pulsed laser
light, commonly referred to as LIDAR, rather than
radio waves. Modern radar detectors have been
modified to alert to the infrared light emitted by
such LIDAR guns. LIDAR detection, however, is not
nearly as effective as radar detection because the
output beam is very focused. While radar's radio
waves can expand to 85 feet across at 1000 feet from
their source, LIDAR's light beam expands to only
about 6 feet. Also, a police officer targeting a car
will most likely aim for the center mass or
headlight of the vehicle and, because radar
detectors are mounted on the windshield away from
the beam's aim, they may not alert at all. Lastly,
with such a focused beam, an officer using a LIDAR
gun can target a single car in close proximity to
others at ranges of up to 3000 feet. Despite the advent of LIDAR speed detection,
radar remains more prevalent because of its lower
price relative to LIDAR equipment and the amount of
radar equipment already in service. Popularity of
LIDAR speed detection is on the rise, though, as
costs decline, ease of operability approaches radar,
and existing radar equipment reaches its
end-of-service life and is rotated out of service. Although some companies advertise that their
radar detectors can 'scramble' or 'absorb' radar and
LIDAR (such as Rocky Mountain Radar), many or all of
their products do not affect radar and laser
equipment due to the low power intake from the
device versus the high power that bounces off a
vehicle. In the USA, it is illegal to sell or possess any
such products that do transmit radar signals
intended to jam radar equipment. Actively
transmitting on an FCC licensed frequency without a
license is a violation of FCC regulations and a
felony. LIDAR jammers are legal in most states and
are regulated, much like police LIDAR guns, by the
FDA as Class I laser devices.
