ABSTRACT:
A velocity measurement apparatus using pulsed ultrasonic waves which includes a transmitting section which projects pulsed ultrasonic waves to a target at a predetermined position and a receiving section which detects echoes from the target and the Doppler shift. The transmitting section, in order to remove undesirable echoes, causes the polarity of the ultrasonic pulse to be changed at random and the receiving section removes the undesirable echoes by using the irregular polarity of the pulsed ultrasonic echoes.
