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 ...
This is a list of World War II electronic warfare equipment and code words and tactics derived directly from the use of electronic equipment.. This list includes many examples of radar, radar jammers, and radar detectors, often used by night fighters; also beam-guidance systems and radio beacons.
An early radar detector Car radar detector (Japanese) A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding.
Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat.
This low-cost detector has impressive range and all the requisite features, including GPS for low-speed false-alert muting, manual marking of up to 100 known radar locations, and speed-camera alerts.
In the radar receiver, the returning echoes are typically received by the antenna, amplified, down-converted to an intermediate frequency, and then passed through detector circuitry that extracts the envelope of the signal, known as the video signal. This video signal is proportional to the power of the received echo.
The Type 346 was developed by the Nanjing Research Institute of Electronics Technology [nb 1] Further development may have been assisted by the examination of foreign technology; the Type 051C destroyers used 30N6EI Tombstone phased-array Flap Lid antennae from Russia, and in 2004 a prototype C band active phased-array radar and its design package were purchased from the Kvant Design Bureau of ...
