PROBLEM TO BE SOLVED: To provide a wind measuring apparatus capable of suppressing deterioration of wind measuring accuracy even when oscillation is comparatively large.SOLUTION: In a distance difference calculating unit 7, by using beam scan angle information from an antenna control unit 4, oscillation information from an oscillation detection unit 5, and measuring point information from a measuring point calculation unit 6, a distance difference in measuring points between in an originally-oriented visual direction and in a post-oscillation visual line direction which is an actually oriented visual line direction is calculated. A measuring point selection unit 8 extracts a measuring point in the case where the distance difference is within a predetermined distance, and Doppler information thereon. A wind information calculation unit 9 calculates wind information in a predetermined observation region on the basis of Doppler velocity of the Doppler information selected by the measuring point selection unit 8 and the beam scan angle information. |
