Radar Detector FAQ
A radar device, such as a radar speed-sensing implement, emits radio waves to determine the speed of a vehicle. It measures the distance that the radar wave has to go before it bounces back, then calculates the speed of a vehicle based on the distance.
A radar detector detects these radar waves. It works like a radio receiver. The radar detector looks for a radar signal and warns you when it locates one.
