The Physics of Radar Guns The Hardball Times

Web2 days ago · When a radar is used to detect the speed of an object (for example, when a police officer with a stationary radar gun is detecting the rate at which a car is moving), it does so by taking advantage of a phenomenon that occurs whereby the frequency of the radio wave for the return signal is altered because of the car’s motion relative to the radar. WebDec 9, 2024 · How Does A Police Radar Detector Work. Radar detectors are used to detect the presence of police radar guns.
