Millimeterwave radar sensors use millimeterwave. Usually millimeter wave refers to the 30~300GHz frequency domain (wavelength 1~10mm). Among them, the 24GHz radar sensor and 77Ghz radar sensor are mainly used for automotive collision avoidance.

The wavelength of millimeter wave is between centimeter wave and light wave, so millimeter wave has the advantages of both microwave guidance and photoelectric guidance. Compared with centimeter-wave radar, millimeter-wave radar has the characteristics of small size, easy integration and high spatial resolution.

Compared with optical sensors such as cameras, infrared, and lasers, millimeter-wave radar has a strong ability to penetrate fog, smoke and dust, has a strong anti-interference ability, and has the characteristics of all-weather (except heavy rainy days) throughout the day.
