Abstract
A transmission wave is transmitted to a target from a transmission section. A receiving section receives a wave reflected from the target as a received wave. A conversion section converts a time difference between the transmission time at which a transmission wave is transmitted and the receiving time at which a received wave is received in to a voltage. The thus-obtained voltage is subjected to analog-to-digital conversion by means of a processing circuit, whereby a distance is computed.
