ことを特徴とする車両のスキヤニングソナー。[Scope of Claim for Utility Model Registration] In a vehicle scanning sonar that detects obstacles around the vehicle by rotating an ultrasonic unit mounted on the vehicle to perform scanning, the received signal is the reflected wave from the vehicle itself. Reference signal storage means for storing a received signal received when there is no obstacle at a search position of the ultrasonic unit as a reference signal, and subtracting the stored reference signal from the received signal at the search position. A scanning sonar for a vehicle, comprising a subtraction means and a determination means for determining the presence or absence of an obstacle at the search position based on the subtraction result.
