摘要： A light wave radar apparatus includes a frequency deviation detecting unit 12 for detecting a frequency deviation f chirp of a light signal, and a weighted average processing unit 13 for determining a systematic error ”V offset from the frequency deviation f chirp detected by the frequency deviation detecting unit 12, and subtracts the systematic error ”V offset 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.

摘要： A radar system, a radar device, and an interference avoidance method are obtained that can utilize frequency effectively even in three or more radar devices. The present disclosure relates to interference avoidance between three or more radar devices 1 arranged to have an overlapping scanning/radiation range being a range at which a scanning range of radar device 1 overlaps with the scanning range or a secondary radiation range of each of other radar devices 1, the same overlapping scanning/radiation range being overlapped by each of the three or more radar devices, the scanning range and the secondary radiation range of the radar device that are ranges in each of which the radar wave, is transmitted and is received by radar device 1 while an orientation direction is changed. A radar system 50 includes three or more radar devices 1 and a schedule management controller 6. Schedule management controller 6 predicts an interference time period that is a time period during which the overlapping scanning/radiation range is generated, determines a first interference avoidance measure that is a measure to make radar devices 1 to use respective different use frequencies while keeping a restriction on the number of frequency channels, in the predicted interference time period, and determines a second interference avoidance measure to be performed by a radar device that is unable to avoid interference by the first interference avoidance measure.
