Rear parking radar refers to the parking radar installed at the rear of a vehicle. If a car is equipped with a rear parking radar, the radar detectors can be seen on the rear bumper. The parking radar is a very useful device that detects the distance to obstacles behind the vehicle when reversing. If the distance is too close, it will emit a warning sound to alert the driver. The working principle of the parking radar is very simple: the radar probe emits sound waves, which are reflected back when encountering obstacles. The radar probe can calculate the distance between the obstacle and the rear of the car based on the time it takes for the sound waves to be reflected back.
