Abstract:
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 disclosure 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.

Claim (Index 7):
The laser radar device according to  claim 6 , wherein, when a time difference between the pulse trigger signal outputted by the optical modulator and the timestamp of the motion amount is greater than a predetermined threshold, the signal processor uses an estimated value of the motion amount in the correction of the spectra of the received signals.
