An ultrasonic sonar has a transceiver equipped with an ultrasonic oscillator. An ultrasonic wave is transmitted from the transceiver. The ultrasonic wave reflected from an obstacle is received by the ultrasonic oscillator to detect the obstacle. The transmission frequency of the ultrasonic wave is set to be different from the reverberation frequency. When the obstacle is detected, a microcomputer converts the analog signal received by the ultrasonic oscillator into a digital signal, performs a frequency transform of this signal by Fourier transform to extract only the transmission frequency component, and performs an inverse transform.
