A radar detector is an electronic device used by drivers to determine if their speed is being observed or not by a policeman. The purpose of a radar detector is to protect the rider from getting a speeding ticket from the officer using a radar gun.

 Radar is a system used to measure the speed and location of any object. The system consists of two main parts – a transmitter and a receiver. Radio transmitters cause voltage fluctuations by an oscillating electric current at a predetermined frequency. This oscillation of the electric field generating electromagnetic energy.

This electromagnetic energy propagating in air as electromagnetic waves. A transmitter consists of an amplifier and an antenna. While the former increased the strength of the electromagnetic energy, the last transit was in the air.

The basic function of the radar is to determine the distance of objects destined. For this function, the radar device emits radio signals integrated to observe any echo. If an object comes in the way of radio waves, it can be easily detected by radar with the help of electromagnetic energy.

Continuous radio waves traveling through the air at the speed of light. The distance of the object from the radar is determined by observing the time it takes for radio waves to return.

To measure the actual speed of any object, the radar can be used to the fact that so-called Doppler shift. When a moving object passing in front of the radar, echo would reflect radar signals. The time it takes radio signals to return after striking an object, and the frequency with which they are traveling, give the actual speed of that object.

A radar detector detects police radar base with just a simple radio receiver. Instead, a more sophisticated detector consisting of a basic receiver along with a radio transmitter. A jamming signal is generated through this transmitter. It blends the signal from the police radar gun with extra radio noise. Because of this, confused echo signal received by the police radar gun, and precise reading speed can not be retrieved.

Light-sensitive panel used in modern detectors that detect light from police laser guns. Lidar is difficult to avoid because the beam is concentrated, so it is possible that at the time of the detector is able to detect it, the vehicle is in sight beam it already. To that end, speeders also use a laser jammer. It works like a radar jammer.
