摘要： The range finder includes a transmitting unit (71) which emits a transmitted wave (75) spread using a spread code at a constant chip rate, a receiving unit (72) which receives a reflected wave (76), a correlation unit (73) which calculates a correlation waveform indicating delay time and a correlation between the transmitted wave (75) and the reflected wave (76), and a distance calculation unit (74) which calculates, from a peak position in the waveform, a distance to the object. The correlation unit (73) calculates the correlation waveform obtained when changing the delay time for each range gate. The distance calculation unit (74) calculates the distance to the object by calculating, at a resolution finer than the range gate, a delay time corresponding to the peak in the correlation wave using a highest-correlation point and an adjacent higher-correlation point in the wave form.
