OPERATION DETAILS
A proliferation of radar devices using KA band frequencies began in 1987 with the
introduction of photo radar (34.3 GHz) and was followed by the Stalker (34.2~35.2
GHz) in 1991 and the BEE 36A (33.4~34.4 GHz) in 1992.
Early detectors needed only to listen for X band radar. When K band arrived, dual band
detectors able to receive both frequencies (X and K) were required. The introduction of KA
band photo radar (34.3 GHz) led to the development of tri-band detectors able to detect X, K,
and a small portion of KA band. A fourth category of radar receivers called “wide-band” with
X, K, and wide KA (34.2~35.2 GHz) band detection capabilities reached the market following
the introduction of Stalker radar. Finally, in response to the BEE 36A, a new generation of
“superwide-band” radar detectors was developed. They detect all radar devices operating
on X, K, and superwide KA (33.4~36.0 GHz) band. All SENSORO radar/laser detectors are
superwide band receivers.
Laser devices transmit an invisible light beam at a frequency (more accurately a
“wavelength”) of 904 nanometers. A nanometer is how a light wavelength is measured.
Different laser devices operate at different light pulse rates and some manufacturers call them
“bands”. All SENSORO radar/laser detectors can detect all current laser devices in use.
Less than 1,000 laser devices are in service in 45 states at present. Most are used by city police
on urban multi-lane roadways. The use of laser devices for speed monitoring is expected to
increase, but will remain limited due to their high cost and limited attractiveness to agencies
that favor the convenience, offered by conventional moving radar. Currently, laser guns
account for less than 5% of the total number of speed monitoring devices (radar and laser)
sold in the U.S. annually; during the next five years, this figure is expected to remain under
8%. Laser devices will likely be in service in every state within a few years.
