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.

摘要： A shape measurement instrument includes a plurality of transmitters 1 to 4 which radiate signals having different waveforms or phases, receivers 31 to 34 which receive signals reflected from an object O, correlation units 41 to 44 which obtain correlation waveforms between waveforms of the signals received by the receivers 31 to 34, and the signal radiated by a transmitter radiating the received signal of the transmitters 1 to 4, and a shape estimation unit 5 which extracts a quasi-wavefront based on the correlation waveforms obtained by the correlation units 41 to 44 and estimates a shape of the object O based on a relationship between the quasi-wavefront and the object O. As a result, a period of time required to measure an object shape can be significantly reduced.
