Abstract
In view of the poor accuracy of buoy estimation and tracking results caused by ignoring the influence of the marine environment on buoys in the current tracking process of ocean drifting buoys, a tracking method of ocean drifting buoys based on spectrum analysis is proposed. By calculating the disturbing force and moment of the ocean current on the ship, the relative operating characteristics between the drifting buoy and the ocean current are obtained, and the ocean current motion model is constructed; According to the Newton Eulerian dynamic equation, the acceleration and external force of the floating body are calculated, and the motion spectrum characteristics of the floating buoy are extracted; According to the result of feature extraction, the trajectory of ocean drifting buoy is located and tracked by Kalman filter. So far, the tracking of the ocean drifting buoy is completed. The experimental results show that the tracking accuracy of this method is up to 100% without interference, and 99.81% with interference.
