Načelo obratnega radarja

‌The working principle of reversing radar is based on ultrasonic ranging technology, and is mainly composed of ultrasonic sensors (commonly known as probes), controllers and displays (or buzzers). When the vehicle enters the reverse gear, the reversing radar system automatically starts, and the ultrasonic sensor begins to emit high-frequency ultrasonic Signali . Ti signali se bodo odražali nazaj, ko bodo naleteli na ovire in jih prejeli isti senzor ali sosednji senzorji . Po prejemu odsevnega signala ga krmilnik pretvori v informacije o razdalji z izračunom časov
