Abrégé

In the present invention, a transceiver emits radar waves at predetermined time intervals when a mobile body device is in movement, and receives radar waves that have been reflected by a reflecting object. A reflection location analyzer determines the relative position of the reflecting object relative to the location of the radar device on the basis of the received radar waves. A storage device stores a history of relative positions of the reflecting object that have been determined. An obstacle identifier determines whether or not the reflecting object is an obstacle on the basis of the stored history of relative positions of the reflecting object. The obstacle identifier determines the reflecting object to be an obstacle if the relative position of the reflecting object changes regularly at a speed within a predetermined range and in a direction within a predetermined range over a predetermined time length, and determines the reflecting object not to be an obstacle when the foregoing is not the case.
