Abstract

PURPOSE:To cut off inputting of unnecessary information and make the constitution of a device for preventing collision using a radar simple by limiting the scanning range of the radar in relative bearing directions to a prescribed range. CONSTITUTION:When the spread angle theta of the radio waves emitted from a radar horn 4 for FM-CW or the rotating angle of the horn 4 is limited, the sanning range is limited to 110 deg. respectively on the right and left in relative bearing, and the unnecessary inputting from behind, etc. is cut off. The received signals go through BFPs 11-15 corresponding to relative speeds, LED indicators 21-25 for displaying relative distances, etc., and are applied to control circuits 10-, by which stearing, etc. for the purpose of preventing collision are controlled and the generation of an alarm and the like are accomplished. The need for correspondence to excess functions is eliminated and the constitution of the device for preventing collision is made simple by this system of controlling input information by limiting the scanning range.
