摘要： The problem with a conventional laser radar device is that the SNR of a value of a wind speed degrades due to motion. A laser radar device according to the present invention includes: an optical oscillator to emit laser light; an optical modulator to modulate the laser light generated by the optical oscillator; an optical antenna to emit the laser light modulated by the optical modulator into the air, and to receive, as received light, scattered light scattered by an irradiation target; an optical receiver to perform heterodyne detection on the received light received by the optical antenna; a sensor to detect one or more motion amounts of the optical antenna; and a signal processor to calculate spectra of respective received signals obtained by the heterodyne detection performed by the optical receiver, to correct the spectra by using the one or more motion amounts detected by the sensor, to perform an integration of the corrected spectra, and to calculate a speed of the irradiation target from a spectrum resulting from the integration.

摘要： A noise spectral differential unit 10 records a noise spectrum in a state without any received signal, and subtracts the noise spectrum from a received signal spectrum. An offset corrector 11 performs offset correction of the signal spectrum obtained by subtracting the noise spectrum by the noise spectral differential unit 10 with respect to the noise level at a frequency separated from the frequency peak position of the received signal by a prescribed value. A frequency shift analyzer 12 executes signal processing of the signal spectrum resulting after the offset correction and measures a frequency shift. A wind velocity converter 13 makes wind velocity detection from the frequency shift measured by the frequency shift analyzer 12.
