Parking radar systems use Ultrasonic Sensors to transmit and receive ultrasonic signals, enabling real-time detection of the distance and position of obstacles around the vehicle. This helps drivers monitor the surrounding environment when reversing or parking.

Ultrasonic Sensors offer non-contact detection, fast response, and high reliability, making them well suited for automotive applications. They are widely used in various Advanced Driver Assistance Systems (ADAS) to provide a safer and more convenient parking and reversing experience.
