Abstract: PROBLEM TO BE SOLVED: To provide an object detecting device which can accurately recognize a plurality of objects by judging the existence of an omission of either one of combined ascending- and descending side peak frequencies and, when the omission is judged, supplementing the omitted peak frequency by calculating the non-omitted peak frequency based on the omitted peak frequency. SOLUTION: A peak frequency detecting means 14 detects such a spectrum that its level becomes the highest at a prescribed threshold or larger based on spectral data obtained by means of a frequency analyzing means 13 through a frequency analysis and judges such a spectrum that its level before and after the detected spectrum turns to a decreasing trend from an increasing trend as the peak spectrum. An arithmetic processing means 15 makes a plurality of objects to be distinguishable by computing the distances to the objects on all combinations of the ascending- and descending-side peak frequencies obtained by means of the detecting means 14 and, at the same time, comparing the calculated distances with predicted distances. However, when either one of the combination of the ascending- and descending-side peak frequencies is omitted, the arithmetic processing means 15 makes supplement based on the non-omitted peak frequency.
