摘　　要：当证据强冲突时,D-S证据理论会因其归一化过程产生与常理相悖的结果。针对该问题,通过引入相似性测度,对证据源进行特征提取,提出了基于证据相似性测度的目标识别方法。仿真实验表明在传感器受干扰时新方法比别的方法能更快的识别出目标,并且提高了合成证据的可靠性和合理性。When evidences conflict strongly,illogical results are got by using D-S evidence theory. A new method based on similarity measure of evidences was put forward,which extracts intrinsic characteristics of existing evidence sources by using evidence similarity measure.Compared with the existing methods,our new method is more efficient in combining conflict evidence,and the results of the combined evidences are more reasonable and reliable.
