摘　　要：雷达个体识别即雷达指纹识别,是雷达对抗侦察的最终目的,也是现代电子对抗领域的难点。目前在用哪些物理量可以表征雷达信号的指纹特征问题上还存在争论,没有系统的理论。从脉冲包络上升沿方面进行分析研讨,提出一种利用上升沿进行基于多脉冲乃至单脉冲的雷达个体识别方法。仿真结果表明,在一定信噪比下该方法具有可行性。The specific emitter identification（SEI） is radar dactylogram identification,is the final goal of radar countermeasure and reconnaissance,and is the difficulty in modern electronic countermeasure.At the present time,there is still controversy about using which parameters to represent the dactylogram characteristics of radar signal,and there is no systematic theory.This paper performs the analysis and discussion from the aspect of the pulse envelop rising-edge,presents a kind of radar SEI method based on multi-pulse even single pulse by using rising edge. The simulative re suit shows that the method has feasibility in the condition of proper signal noise ratio.
