Fishpond – British fighter warning radar add-on to H2S, fitted early 1944 to some bombers. Flensburg – FuG 227, German radar detector fitted to night fighters to detect the British Monica tail warning radar transmissions. Freya – German ground based air search radar. G–H – British radio navigation system used for blind bombing, from TRE.
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 ...
A radar with a wavelength of 2 meters (VHF band, 150 MHz) cannot detect objects that are much smaller than 2 meters and requires an antenna whose size is on the order of 2 meters (an awkward size for use on aircraft). In contrast, a radar with a 10 cm wavelength can detect objects 10 cm in size with a reasonably sized antenna.
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.
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.
AN/APQ-50 is the radar installed on low-rate initial production batch of F-4s, but as with earlier radars, it was not used in great numbers in comparison to later radars of the same family. The parabolic antenna is 24 inches in diameter, and in addition to providing all weather capability, AN/APQ-50 FCR also provides information on automatic ...
The APG-71 was a 1980s upgrade of the AWG-9 for use on the F-14D Tomcat.It incorporates technology and common modules developed for the APG-70 radar used in the F-15E Strike Eagle, providing significant improvements in (digital) processing speed, mode flexibility, clutter rejection, and detection range.
