Abstract A shipborne platform wind speed measurement correction method is provided, comprising: establishing a geodetic coordinate system, a ship coordinate system, and relative coordinate system; determining a position coordinate of a fixed anemometer on the ship in the ship coordinate system, and obtaining a measured wind speed in real time; real-timely acquiring the ship navigation parameters through fixed sensors on the ship; calculating a conversion matrix and an inverse matrix of the ship heading, the heeling angle and the trim angle in three coordinate systems; respectively calculating a wind vector generated by ship rolling, ship pitching and ship steering, and accordingly calculating a relative wind velocity vector generated by ship sloshing; calculating a sloshing error caused by the relative wind velocity vector; and calculating to obtain a corrected real wind speed according to the measured wind speed, the sloshing error and the ship speed. Establishing a geodetic coordinate system based on a geodetic direction, establishing a ship coordinate system based on a center of gravity of a ship and a ship heading when the ship is horizontally stationary, and establishing a relative coordinate system based on the center of gravity of the ship and the ship heading when the ship is tilted; determining a position coordinate of a fixed anemometer on the ship in the ship coordinate system, and obtaining a measured wind speed in real time; real-timely acquiring a ship speed, a ship heading, a heeling angle, a trim angle, a rolling angular velocity, a pitch angular velocity and a steering angular velocity through fixed sensors on the ship; calculating a conversion matrix and an inverse matrix of the ship heading, the heeling angle and the trim angle in three coordinate systems; respectively calculating a wind vector generated by ship rolling, ship pitching and ship steering, and calculating a relative wind velocity vector generated by ship sloshing; calculating a sloshing error caused by the relative wind velocity vector generated by the ship sloshing to a measurement result of a sensor; calculating to obtain a corrected real wind speed according to the measured wind speed, the sloshing error and the ship speed.
