<p><P>PROBLEM TO BE SOLVED: To provide an object detection method certainly detecting an object at point-blank range with a radar device. <P>SOLUTION: The method includes the steps of: setting a dummy target at a position of the same direction as a detected target and of double distance of the detected target; setting a double wave target detection range in a predetermined range including the position of the dummy target; determining a target detected in the double wave target detection range as a double wave target; setting an interpolation target at a position of the same direction as the double wave target and of a half the distance of the double wave target; setting a fundamental wave target detection region in a predetermined range including the position of the interpolation target; and output of the interpolation target as a fundamental wave target when no fundamental wave target is detected in the fundamental wave target detection region. Thus, even if the fundamental wave target to be detected comes into a non-detection state in point-blank range, the fundamental wave target can be continuously detected by estimating data of the fundamental wave target with the interpolation target calculated from the still detected double wave target and for output of it. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
