More information on radar detector radar detector Radar detectors were introduced in the early 1970s. The term radar detector originated from technologies that were used previously to sense speed. Now the question arises, 'What is radar?' Radar is a system used to measure the speed and position of any object. This system consists of two significant parts - a transmitter and a receiver. The radio transmitter causes voltage fluctuation by oscillating an electric current at a predefined frequency. This oscillation of the electric field generates electromagnetic energy. This electromagnetic energy propagates in the air as electromagnetic waves. A transmitter consists of an amplifier and an aerial. While the former increases the power of electromagnetic energy, the latter transits it into the air. Circumvent expensive speeding tickets with a radar detector.
