<p>PROBLEM TO BE SOLVED: To minimize erroneous detection, and allow to trace an object even when a vehicle moves in a collision avoiding device. SOLUTION: A first returns from objects 102A, 102B in the visual field of a detection device are received. A current frame of a data point is produced by a sensor. The objects 102A, 102B in the visual field are expressed by plural data points. The data points are converted into global coordinates, next are mapped in the next frame of the data points, and in a next sample time a new current frame of the data points are produced. The new frame is processed so as to contain one piece or more of information from preceding frame. A list of objects having locations and power information is made. By this mapping and processing weak signal targets in such as environment as scattering on the ground are detected by the device 108 so that the occurrence of erroneous detection can be minimized.</p> |
