The Whistler Group was an electronics company based in Bentonville, Arkansas, [1] best known for its radar detectors. Whistler also manufactured power inverters, GPS navigation devices, inspection cameras, LED flashlights, vehicle dashboard cameras, and scanner radios. [2] The company went out of business in 2024 without warning.
Metox – metre-wavelength ASV radar detector fitted to German submarines; Meacon – Masking BEACON - British long wave jamming station - see Meaconing. M.F. D/F (Medium Frequency Direction Finding) - provided a radio position fix for the RAF up to 230 miles from the transmitters in Britain. The system was based on voice communications. [10]
Dodge David Morgan (January 15, 1932 – September 14, 2010) was an American sailor, businessman, publisher and "self-proclaimed contrarian." [1] He flew fighter jets in the U.S. Air Force in the early 1950s, worked as a newspaper reporter in Alaska, and became a millionaire by operating Controlonics, a company that manufactured Whistler radar detectors from 1971 to 1983.
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.
RAD 480i. For those looking for low-cost but suitable protection from police radar, the Cobra RAD 480i provides the basics, including detection of all radar bands and laser signals.
Radar transmission frequency spectrum of a trapezoid pulse profile Recent advances in signal processing techniques have made the use of pulse profiling or shaping more common. By shaping the pulse envelope before it is applied to the transmitting device, say to a cosine law or a trapezoid, the bandwidth can be limited at source, with less ...
Most of today's radar detectors detect signals across a variety of wavelength bands: usually X, K, and K a. In Europe the K u band is common as well. The past success of radar detectors was based on the fact that radio-wave beams can not be narrow-enough, so the detector usually senses stray and scattered radiation, giving the driver time to ...
With the advent of radar by the Signal Corps it was possible to track a radar target carried by the balloons with the SCR-658 radar. Modern radiosondes can use a variety of mechanisms for determining wind speed and direction, such as a radio direction finder or GPS. The weight of a radiosonde is typically 250 g (8.8 oz).
