摘要： 雷达目标识别中多源信息融合面临各种不确定冲突信息。为此，提出一种基于置信距离的冲突证据合成方法。在不改变D-S证据组合规则的前提下，考虑到证据之间的关联性，通过计算证据间的相似度和可信度，利用可信度的加权平均来代替冲突证据，从而消除冲突证据并进行信息融合。仿真实验结果证明，该方法能有效进行冲突证据的合成。

Abstract: Because of the uncertain conflicting information confronted by Multi-source information fusion in radar target recognition, a new conflict evidence integration method based on confidence distance is put forward. This new method takes the relevance of evidence into consideration under the premise of not changing the D-S combination rules, by computing the similarity and credibility of the evidence and using the weighted average of the credibility to replace the conflicting evidence, in order to eliminate the conflict evidence and integrate the information. This method is compared with some existing methods through simulation, which indicates that it is an effective method in conflict evidence integration.

Key words: evidence theory, information fusion, conflict evidence, confidence distance, target recognition, combination rule
