A Relative Optimal Evaluation Algorithm Based on Shipborne Anemometer Layout

In maritime military activities, the real-time information of sea surface wind field is very important to improve the capability of air and sea cooperation in combat. Accurate wind speed and direction data on the surface of the ship can provide important guarantee information for the takeoff and landing of the shipborne aircraft. The buildings on the ship and the layout of the shipboard anemometer will have an impact on the anemometer measurement results, so it is crucial to study the optimal layout of the shipboard anemometer. In this paper, a relative optimal evaluation algorithm based on shipborne anemometer layout is proposed based on the simulation model established by CFD (Computational Fluid Dynamics). Firstly, the correlation between the anemometer and the target anemometer at different positions is used as the main evaluation index, and the average absolute error of the wind direction of the anemometer is combined to obtain the optimal position of the anemometer. Secondly, according to the selected optimal location, eight anemometer layout schemes are proposed. Then, in order to finally arrive at the relatively optimal anemometer layout scheme. The improved multi-sensor fusion algorithm is used as the evaluation method, and the average relative error of wind speed and the average absolute error of wind direction are used as the evaluation criteria. The final results show that the layout of the fifth scheme (four anemometer) is: (0m, 8m, 11.5m), (0m, -8m, 11.5m), (-4.4m, 8m, 11.5m), and (-4.4m, -8m, 11.5m) is the relative optimal layout scheme of the anemometer.
