Abstract:
Included are: a fast Fourier analyzer to obtain a received spectrum for each of time gates by performing fast Fourier transform on a received signal for each of the time gates; a signal integration determiner to determine necessity of integration of the received spectrum obtained by the fast Fourier analyzer for each of the time gates; a spectrum integrator to perform integration of the received spectrum obtained by the fast Fourier analyzer depending on a determination result by the signal integration determiner; a frequency shift calculator to calculate an amount of a frequency shift with respect to the laser light emitted by the optical transceiver from the received spectrum integrated by the spectrum integrator; and a wind speed calculator to calculate the wind speed in a direction in which the laser light is emitted by the optical transceiver from the amount of the frequency shift calculated by the frequency shift calculator.

Claim (Index 1):
A coherent lidar comprising:\n an optical transceiver to obtain a received signal by emitting laser light of a single frequency into an atmosphere, receiving scattered light from the atmosphere, and performing heterodyne detection; an A/D converter to convert the received signal obtained by the optical transceiver into a digital signal; a processor to execute a program; and a memory to store the program, when executed by the processor, causes the processor to perform the processes of: obtaining a received spectrum for each of time gates by performing fast Fourier transform on the received signal converted into the digital signal by the A/D converter for each of the time gates; determining necessity of integration of each of the obtained received spectra; performing integration of the obtained received spectra depending on a result of the determination; calculating an amount of a frequency shift with respect to the laser light emitted by the optical transceiver, from a received spectrum obtained by integration; and calculating a wind speed in a direction of emission of the laser light from the optical transceiver, from the amount of the calculated frequency shift calculated by the frequency shift calculator.
