摘要
雷达发射机的识别问题就是要利用接收到的雷达信号来进行目标电子系统的识别。基于时频分析的性质,提出了一种雷达发射机的识别方法,即利用模糊函数对多个雷达发射机的信号进行时频分析。在本试验中取每一个雷达信号的几个样本模糊函数的均值作为目标特征向量,用最近邻法对其他样本信号做了识别试验,利用此方法能够得到很高的识别率和很好的识别效果。本方法在军事应用上有很重要的意义,可以对敌机进行识别、跟踪。
The basal problem about radar transmitter identification is radar signals that are accepted to identify objective electronic system.The time frequency distribution of radar signal has been analyzed by ambiguity function based on quality of time frequency analysis.Extracting the average of some ambiguity functions as the characteristic vector,using the nearest distance identify the left signal.This paper applies this method for target recognition,and gets satisfactory result.It has very important meaning in military affairs,and also can identify enemy′s airplane and track.
