ABSTRACT:
An inclination angle measurement apparatus includes a first ultrasonic sensor (3) for sending an ultrasonic wave toward a reflective object (2), second and third ultrasonic sensors (4and5) each for receiving an ultrasonic wave reflected from the reflective object (2), and a calculation control circuit (14) for calculating an angle of inclination of a moving object with respect to the reflective object (2) based on a phase difference between ultrasonic waves received by the second and third ultrasonic sensors (4and5). Thus the inclination angle measurement apparatus can accurately measure the angle of inclination of the moving object with respect to the reflective object (2).
