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 ...
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.
Thor III dismounted CREW system: The Thor III system consists of three dismounted man-pack subsystems, one battery charger, and twenty-four batteries (BB-2590/U). Each subsystem contains a R/T (low band, mid band or high band), a Remote Control Unit (RCU), an integration/pack frame, an Rx/Tx Antenna (low band, mid band, or high band), a GPS ...

The Blighter B202 Mk 2 radar from Blighter Surveillance Systems (a Plextek Group company) is an advanced E-Scan radar with no moving parts for high reliability in the field. Its weight is about 15 kg and is therefore truly man portable, about the weight of a machine gun and less than half the weight of other man-portable radars.
The radar speed gun was invented by Bryce K. Brown of Decatur Electronics in March 1954,[2] and was first used in Chicago, Illinois in April 1954.[citation needed] Patrolman Leonard Baldy was the first officer to issue a speeding ticket using the new device.
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.
