摘　　要：目标识别匹配是跟踪制导雷达与动能拦截器成功交班的关键环节.从目标匹配角度,对雷达与导引头之间的交接问题进行了研究.首先提取和量化弹道目标典型识别特征,将每个特征作为一个证据,构造每个证据的基本置信指派函数,然后运用DS方法进行分布式计算融合,通过决策规则对融合结果进行判断,完成目标匹配.最后,用算例验证了DS方法对目标交接的有效性.Target recognition and matching is the key link for proper handoff of tracking-and-guiding radar to kinetic energy interceptors （KEI）. This paper deals with the handoff between radar and seeker from the perspective of target matching. First, the typical identification characteristics of ballistic targets are extracted and quantized, each feature is taken as an evidence and its basic belief assignment function is constructed. Then the distributed computation fusion is performed by using the Dempster-Shafer （DS） method, the fusion results are judged by decision-making rules and target matching is achieved. And finally, the effectiveness of DS method on target handoff is proved by taking computation examples.
