摘要
在分析了D-S合成规则中存在问题的基础上,提出了一种修正D-S融合方法,该方法不但能处理相互冲突证据,而且能够根据焦元包含元素的多少决定向下聚焦的权重的缺陷.同时,在分析巡航导弹攻防对抗研究信息融合系统结构的基础上,将修正的D-S应用到对巡航导弹预警融合节点和拦截融合节点的目标识别中.仿真结果表明了修正的D-S规则在解决巡航导弹目标识别中的有效性.
Based on the shortcoming analysis of Shafer-Dempster method, an arnendatory method was presented. The method can deal with not only the problem of evidence conflict, but also the problem, focused weight downward rigorous regard to the size of subsets, that is basic probability mass can be focuses ＂downward＂ onto smaller subsets if so warranted. And then, after the structure of defense information fusion system of cruise missiles is analyzed, the amendatory method was used to deal with cruise missile＇ s target identification of prewarning and interception nodes. The simulation results certified that amendatory D-S rule is an effective method in the problem of cruise missile＇ s target identification.
