中文摘要：

分析了导弹目标的距离像特性,指出导弹目标距离像可作为识别的特征信号。阐述了置信度原理,根据导弹目标距离像识别的特点提出了一种适用于高分辨距离像识别的置信度函数,进而提出了距离像序贯识别方法。该方法通过相邻距离像的相关系数鉴别错误关联数据,利用识别置信度分析降低误识概率。进行了相应的仿真实验,实验结果表明该方法能改善识别器的识别性能,尤其在低信噪比下有更明显的优势。

英文摘要：

The high resolution range profiles （HRRP） characteristics of missiles are analyzed. It is found that the HRRPs of missiles can be chosen as the signatures for identification. Based on the confidence theory, a new confidence function is presented, which is suitable for analyzing HRRPs recognition method. And then, method of missile recognition using sequential range profiles is proposed. This method can distinguish false association data by computing match scores of adjacent HRRPs and it can lower error recognition rate by confidence analysis. Simulation results show that the proposed method has higher performance compared with matched-filtering technology, especially when SNR is low.
