Research on the optimization wind model based on angle measurement of meteorological UAVs

在气象无人机现用测风模型的基础上,根据无人机飞行角度的不同,对测量总压、空速与地速的夹角进行了修正,提出了优化的测风模型。并给出了误差计算方法。仿真的不同结果表明:所提出的优化测风模型能有效解决飞行角度变化对测风精度的影响,为提高气象无人机测风精度提供了借鉴。

Based on current wind speed measuring models in meteorological UAVs, the total pressures and the angles between air speeds and ground speeds are corrected according to different flight angles of UAVs, and the optimization wind model is established. The calculation methods of errors are given in the paper too. The simulation results show that： the optimization wind-speed measuring model can reduce the influence of changing flight angles on wind-speed measuring accuracy effectively, and provide a reference method for improving wind-speed measuring accuracy in meteorological UAVs
