| 摘 要： | 增加新的特征参数是提高雷达辐射源信号分选识别率的有效手段。相参是新体制雷达辐射源的重要特性，在现有特征参数的基础上，增加相参特征用于信号分选，对降低当前信号分选“漏警”、“虚警”概率极具价值。在分析新体制雷达辐射源相参特征的基础上，对侦察到的脉冲流进行了信号重构，利用频谱分析的方法，提取了重构信号的频谱主峰㈥像，理论分...

| Abstract: | Adding new characteristic parameters is the effective mean to improve the recognition rate of radar emitter signal sorting.The coherent is an important characteristic of new system radar emitter,on the basis of existing characteristic parameter,new characteristic parameter is added to signal sorting,which is extremely valuable to reduce the probability of leak-alarm and false-alarm in existing signal sorting.This paper reconstructs the signal to the detected pulse flow based on analyzing the coherent charac... |
