摘要
雷达信号个体识别是雷达信号识别领域的研究热点,雷达"指纹"特征参数的选取、雷达"指纹"特征参数的高精度测量以及雷达信号个体识别算法是雷达信号个体识别的3个关键技术。提出了将贴近度运用于雷达信号个体识别中,采用了基于阀值原则与贴近度原则相结合的识别手段,给出了个体识别流程和个体数据库中特征参数权重更新手段。理论分析与计算机仿真表明,该方法是切实有效的。
Radar signal individual identification is a hot issue in radar signal identification area. Its three key technologies are radar fingerprint parameters＂ choice, radar fingerprint parameters＇measurement and radar signal individual identification arithmetic. It is proposed that close degree can be applied in ra- dar individual identification, by combing valve-value principle and close-choosing principle as identification means. Individual identification steps and the ways to update parameters＂ quotients are also presented. Theoretic analysis and computer simulation results indicate that this method is feasible and effective.
