摘　　要：在气象无人机现用测风模型的基础上,重点研究了迎角和航迹倾斜角对测风精度的影响,建立了改进型测风模型。提出了迎角和航迹倾斜角的误差计算方法,并对其进行了仿真分析。结果表明:当迎角|α|≥0.5,°必须对迎角造成的误差进行修正;当航迹倾斜角δ≥2,°必须对航迹倾斜角造成的误差进行修正。Based on the wind model of meteorological UAV in being researched the impact of the angle of attack and the flight-path slope on wind precision,the improved wind model was founded.The established errors calculate method,and the improved wind model of angle of attack and flight-path slope were used for simulation.The simulation results show that： when the angle of attack ｜ α ｜≥0.5 °,the error caused by the angle of attack must be corrected;when the flight-path slope δ≥2 °,the error caused by the flight-path slope must be corrected.
