A radar speed gun, also known as a radar gun, speed gun, or speed trap gun, is a device used to measure the speed of moving objects. It is commonly used by police to check the speed of moving vehicles while conducting traffic enforcement , and in professional sports to measure speeds such as those of baseball pitches , [ 1 ] tennis serves , and ...
Pocket Radar utilizes very similar microwave signal emission and detection methods found in the Doppler speed radar guns used by law enforcement agencies. The device measures 4.7 by 2.3 inches (119 by 58 mm) and weighs 4.5 ounces (130 g) when equipped with two AAA batteries. It operates at the 24.125 GHz K-Band frequency and can measure speeds ...
The speed of a vehicle occluded by (hidden behind) another vehicle cannot be measured. This occlusion issue does not apply to fixed speed enforcement devices that can be mounted on poles or gantries up to 5-6 meters / 15 -20 ft high using radar as detection method. Fixed and handheld lidar systems reliable up to heights of roughly 2 meters / 7 ft.

Radar speed guns use a microwave signal that is directed at a vehicle; the Doppler effect is used to derive its speed. LIDAR speed guns utilize the time of flight of laser pulses to make a series of timestamped measurements of a vehicle's distance from the laser; the data is then used to calculate the vehicle's speed.
