PROBLEM TO BE SOLVED: To provide a method and an apparatus for measuring a wind direction and a wind velocity whereby the wind direction and the wind velocity of an atmosphere can be continuously, easily and inexpensively measured. SOLUTION: While laser beams 21 are emitted like pulses periodically via a predetermined time interval, the laser light is scanned conically to upward of an atmosphere and a reflecting light from the atmosphere is detected by a conical scan apparatus 2. Data of the reflecting light corresponding to the same altitude and the same direction are arranged in time series within a measuring apparatus 4 with the use of the received reflecting light. A plurality of data of the reflecting light on the same altitude are subjected to a correlation operation, whereby a phase difference of the data is obtained. A wind direction, a wind velocity of the atmosphere are measured on the basis of the phase difference. |
