Abstract
The Georgia Tech Research Institute has designed a radar detector detector (RDD) capable of sensing the presence of a radar detector in a moving vehicle at a distance of up to several miles, depending on the terrain. The RDD was designed for use in a radar detector density survey as part an ongoing United States Department of Transportation project to measure the potential impact of the Safety Warning SystemTM on motorists in a work zone. In Canada and the two U.S. states where radar detectors are outlawed, law enforcement uses VG-2 detectors able to sense the leakage of the radar detector's local oscillator (LO). Due to the radar detector industry's stance that a radar detector is simply a radio receiver, the industry responded by adding countermeasure features. One type of countermeasure turns off the radar detector LO when the leakage from the VG-2 LO is detected. Another method reduces the radar detector LO leakage to levels nearly impossible to detect using the VG-2.
