Original Abstract Submitted

A fine section setting unit of a laser radar device sets, for a beat signal waveform indicating time change of a beat signal amplitude of an up beat signal, a plurality of fine sections within time ranges of the beat signal waveform. A fine section extraction unit extracts at least one fine section satisfying a preset extraction condition indicating that the beat signal amplitude in the fine section is high, from among the set plurality of fine sections. A peak detection unit subjects the beat signal in the extracted fine section to frequency analysis to calculate a fine section frequency spectrum and detect a peak frequency, which is a peak in the fine section frequency spectrum.
