Abstract
For data detected by a milltimetric wave radar 2 and an image sensor 3, a signal processor 4 of a peripheral monitoring sensor 1 divides an area in which a detected target exists into a plurality of areas. For a target that exists within a certain specific area, information on the target is prepared based on the information obtained by both sensors. The millimetric wave radar is good at measuring a range and a speed of a target at long range. The image sensor is good at measuring a width and a bearing of a target. Therefore, by combining the data that each sensor is good at obtaining, it is possible to obtain accurate information. The signal processor 4 decides a surface of a target by combining an existing position of the target detected by the millimetric wave radar with target information detected by the image sensor. Thus, a peripheral monitoring sensor is obtained that securely senses a range, a relative speed, and a shape of the target.
