In recent years, some complications have entered into the use of radar for catching speeders. Since about 1974, when high quality radar detectors first came on the market, there has been a "cold war" between designers of police radar equipment used by speeding motorists trying to evade being ticketed. For instance, until late 1975, all police radar operated at 10.5-10.55 GHZ (x-brand); therefore, detectors were designed to be sensitive just to this range. Then, 24.05-24.15 GHZ (k-brand) radar was developed, only to be followed by "dual-brand" detectors. In turn, to get around the use of these detectors as well as the fact that detectors have a wider range (2 miles) then the radar itself (1/2 mile), on/off "keyed" radar which emit no microwave beam until an approaching vehicle has been visually sighted has been developed. Still another gambit is the deployment along expressways of "dummy" radar transmitters operating continuously on the police radar frequencies which are (unbeknownst to the motorist with a detector) unattended. This "cold war" is likely to continue since state and local laws against the use of detectors have not held up in court. From the viewpoint of the law-abiding motorists, there is the problem that radar equipment malfunction and/or inexperience on the part of the operator may lead to incorrect target identification and the ticketing of innocent motorists. Still another problem is the current lack of performance standards for police radar equipment, although this will be eventually rectified as the NHTSA has recently announced that standards will be developed by the NBS Law Enforcement Standards Laboratory.
