改进加权D-S证据理论在目标意图预测中的应用

为了在预警机中准确对目标意图进行预测,以便我方及时合理的作出战术决策,采用D-S证据理论对目标意图进行预测.首先提取出影响目标意图预测的各个态势因素,然后分析每个因素的影响效果.在此基础上建立目标意图预测的数学模型,利用D-S合成法则将所有因素的影响进行综合,并计算出各个可能命题的概率赋值并给出相应决策.仿真实例表明:融合后的不确定概率有较大幅度的下降,得到了合理的目标意图预测结论,文中的方法可扩展为多个目标编队的意图预测.

Application of Dempster-Shafer Evidence Theory to Target Intention Prediction

In order to accurately predict target intention prediction and help decision-making timely and reasonably,the D-S evidence theory is adopted in target intention prediction.First,the situation factors are extracted,and then the influence of each factor is analyzed,based on which,the mathematic modeling is created.With the D-S composition law,the influences of all factors are integrated,the probability evaluates of the likely propositions are calculated and the corresponding decision is made.Numerical example...
