A radar detector detector (RDD) is a device used by police or law enforcement in areas where radar detectors are declared illegal.
Radar detectors are built around a superheterodyne receiver, which has a local oscillator that radiates slightly. It is therefore possible to build a radar-detector detector, which detects such emissions (usually the frequency of the radar type being detected, plus about 10 MHz for the intermediate frequency). Some radar guns are equipped with such a device.
However, like any device that detects stray emissions from electronic equipment, it is easily defeated by using adequate shielding.
