Dempster-Shafer证据理论在目标意图预测中的应用

为了准确对目标意图进行预测,以便我方及时合理地作出战术决策,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。最后,通过仿真实例验证了该方法在目标意图预测中的可行性和实用性。

Application of Dempster-Shafer evidence theory in target Intention prediction

In order to accurately predict the intention of target so as to make decision reasonably in time,the D-S evidence theory is used in target intention prediction.At first,the situation factors that have effect on target intention prediction are extracted,and then the effect of each factor is analyzed.Based on which,mathematic models are set up for target intention prediction.With the D-S composition law,the influences of all factors are integrated together,the probability values of the likely propositions are calculated out.Numerical simulation examples showed that the method of intention prediction is feasible and practical.
