摘要： 针对辐射源目标威胁评估中属性指标权重设计缺乏全面性、评估缺乏动态性等不足,提出基于层次分析法(Analytic Hierarchy Process,AHP)与熵权法组合赋权的逼近理想解(Technique for Order Preference by Similarity to Ideal Solution,TOPSIS)动态辐射源威胁评估方法。首先提出包含平台属性和雷达属性的辐射源威胁评估指标体系;其次构建量化定性和定量属性的威胁隶属度函数;然后通过AHP和熵权法给属性进行主、客观组合赋权;接着利用泊松分布逆形式引入时间权重,融合多时刻信息;最后基于TOPSIS算法求解目标的威胁排序。仿真分析表明,相比主观赋权或客观赋权法评估,所提组合赋权法具有更强的全面性和有效性;相比仅考虑目标当前时刻属性信息评估方法,所提引入时间权重的动态评估方法具有更好的合理性和客观性。所提方法能较好地反映多目标的威胁排序,为作战指挥决策提供有力的依据。
