ABSTRACT:
Disclosed herein is an omnidirectional distance measurement system which transmits and receives ultrasound waves using as many as four transmitting-receiving transducers having specially shaped beamwidths. Through the use of four such ultrasonic transducers, the system may be set up to obtain any beamwidth from 5.degree. up to 360.degree. in both the horizontal and vertical planes. In the preferred embodiment, the present invention is able to detect the distance and direction to up to four objects in a prescribed work area at any one time and may also detect the speed of any one of the objects if desired.
