How do they work?

Radar technologies are always evolving. However, police use current technology on their speed measuring guns to estimate the speed of a moving vehicle. Some of these speed guns are referred to as Doppler radar guns because they utilize the Doppler effect to give a speed reading.

They do so by emitting a radio wave that bounces of your vehicle. The change in frequency after the bounce is what provides the officer with your estimated speed. That can be from a handheld radar gun or a device from fixed devices such as traffic signals.

The radar detector identifies any electromagnetic signals through the help of a superheterodyne receiver which picks up electromagnetic emissions from a Doppler radar gun.

With the addition of GPS technology, these radar detectors can also recognize hot spots where police frequent. You do not need to key in any coordinates, just the touch of a button will mark the place on your detector.

The radar detector will warn you when it detects an electromagnetic signal or when you are approaching a spot frequently manned by police that you have previously saved.

Since the detectors can be affected by speed signs, adaptive cruise control or supermarkets and buildings with automatic door openers, you can mark this false spots manually on your radar detector so that it ignores them the next time you pass there.

The detectors can also be programmed to mute when traveling below a pre-set speed to avoid any alarms.
