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.
Motorway Incident Detection and Automatic Signalling, usually abbreviated to MIDAS, is a UK distributed network of traffic sensors, mainly inductive loops (trialling at the moment radar technology by Wavetronix and magneto-resistive wireless sensors by Clearview Intelligence), which are designed to alert the local regional control centre (RCC) to traffic flow and average speeds, and set ...

Lidar has a wide range of applications; one use is in traffic enforcement and in particular speed limit enforcement, has been gradually replacing radar since 2000. [1] Current devices are designed to automate the entire process of speed detection, vehicle identification, driver identification and evidentiary documentation.
(The fire control radar was the preferred method.) The present position of the target was called the Line-Of-Sight (LOS), and it was continuously sent down to the plotting room by synchro motors. When not using the radar's display to determine Spots, the director was the optical spotting station. [1]
Standard radar speed sign with block letters. Pictured with solar panel.. A radar speed sign or speed feedback sign is an interactive sign comprising a speed-measuring device (e.g. a loop detector or radar) and a message sign generally constructed of a series of LEDs, which displays vehicle speed of approaching motorists.

DFR7. 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 ...
An airport surveillance radar display. A radar display is an electronic device that presents radar data to the operator. The radar system transmits pulses or continuous waves of electromagnetic radiation, a small portion of which backscatter off targets (intended or otherwise) and return to the radar system.
