<p><P>PROBLEM TO BE SOLVED: To estimate the width of a target so as not to cause inconvenience in determining a driving lane in the case that it is impossible to determine the width of the target. <P>SOLUTION: An estimated width value W of the target is computed on the basis of the expression, W=D-2RtanA (wherein, the actual width of the target is D, the distance to the target is R, and a step width of azimuth angle scanning is A). <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
