police radar
Velocity measuring device
Police radar is a speed-detection device used by law enforcement to measure the velocity of moving vehicles.
The device emits radio waves that bounce off approaching or receding cars, calculating speed from the frequency shift.
Drivers use radar detectors to avoid speeding tickets, and speed trap often implies police radar in use.
