Abstract
A distance detecting device having a transmitter for intermittently transmitting measuring waves toward an object, a pair of receivers provided so as to be spaced from each other by half the wave length of the waves in a direction of the object, each receiver receiving reflected waves from the object and transmitting a reception signal responsive to the amplitude of the reflected waves, an addition circuit for adding the reception signal from each of the pair of receivers and transmitting an addition signal, a peak detection circuit for detecting a peak of the addition signal and transmitting a reflected waves reach signal at the time of peak detection, and an operation device for calculating the distance to the object based on the return time from the time when the waves are transmitted to the time when the reflected waves reach signal is outputted.
