The basic theory behind the Parking Assistant is the Sound Navigation and Ranging (SONAR) technique that is used for finding the distance and direction of a remote object underwater by transmitting sound waves and detecting reflections from it. First, a series of short ultrasonic pulses are transmitted using a transducer that changes voltage into sound waves. The transmitted pulse is reflected off an object, and the reflected wave is then received by another transducer that converts sound waves into voltage. The transmitted signal is also known as the ‘ping’ and the received signal is known as the ‘pong’. By counting the elapsed time between the ping and the pong, the distance between the device and an object can be easily calculated by multiplying the elapsed time with the speed of sound.
