摘　　要：分析了影响无人机飞行的恶劣气象条件的特征和特性,建立了恶劣气象条件的模型;确定了各种恶劣气象条件的威胁因子和威胁度,通过定量分析和采用模糊决策算法对综合威胁评估模型进行了计算,得到了综合威胁权重指数;利用实例对评估模型进行了验证。结果表明,该模型能客观反映恶劣气象条件对无人机的威胁程度,可依此判断无人机航迹的优劣。The characteristics of hazardous weather conditions which affect the aviation of the UAV are analyzed and the characteristic model of hazardous weather conditions is built.The threat factor and degree of all kinds of hazardous weather conditions is ascertained.The synthesis threat evaluation model is computed by quantitative analysis and the fuzzy decision-making algorithm and the synthesis threat weighting index is gotten.Simulating the evaluation model using instances and according to the results,this model can reflect the degree that the hazardous weather threats the UAV,and based on this we can judge whether the track of the UAV is good or not.
