Field: Measurement (Instruments)
Classification: CPC G  F  Y | IPC F  G

Claim 1:
2. The laser radar device according to claim 1, wherein the processing circuitry is further configured
to determine whether or not a signal-to-noise ratio of the stored reception spectrum is larger than a threshold,
to calculate a wind speed using a reception spectrum whose signal-to-noise ratio is determined to be larger than the threshold among reception spectra for respective divided sections stored, and
to store a reception spectrum whose signal-to-noise ratio is determined to be equal to or smaller than the threshold, and integrate the calculated reception spectrum when the laser beam is present in a divided section corresponding to the stored reception spectrum with the stored reception spectrum until it is determined that the signal-to-noise ratio is larger than the threshold.
