The electromagnetic wave with a wavelength of 1 to 10 mm is often called millimeter wave (millimeter wave), which is located in the wavelength range of microwave and far infrared wave overlapping, and has the following four characteristics:

Millimeter wave radar is currently mainly used in mid-to-high-end models, and as Volkswagen's trust in the active safety performance of vehicles increases, ADAS-related products will gradually spread to low-end models.

ehicle-mounted millimeter wave radar emits millimeter wave outward through the antenna, receives the reflected signal of the target, and quickly obtains the physical environment information around the car body...

Radar has all-weather, all-day working characteristics, and the detection distance is long, the detection accuracy is high, in the vehicle forward target detection system, plays an important role.
