Basic knowledge of millimeter wave radar
Millimeter wave radar, as the name suggests, is a radar that operates in the millimeter wave (frequency 30~300GHz, wavelength 1-10mm) band. The English name is Radar (Radio Detection and Ranging), which means radio detection and ranging;
Similar to ordinary radar, a Radar measures the distance and relative speed between a vehicle and an obstacle by transmitting radio signals and receiving reflected signals. Millimeter wave radar has some advantages of microwave radar and photoelectric radar, and is very suitable for the application of autonomous vehicle; Millimeter wave radars are often installed behind car bumpers or placards due to their good penetration and ease of penetration through plastic bumpers or placards.
