Abstract:
A light wave radar apparatus includes a frequency deviation detecting unit 12 for detecting a frequency deviation fchirp of a light signal, and a weighted average processing unit 13 for determining a systematic error ΔVoffset from the frequency deviation fchirp detected by the frequency deviation detecting unit 12, and subtracts the systematic error ΔVoffset from a wind velocity VW calculated by a Doppler signal processing unit 11. As a result, the light wave radar apparatus can carry out a measurement of the wind velocity VW with a high degree of precision.
