摘要
提出了以脉冲包络前沿波形作为辐射源的"指纹"进行雷达辐射源个体识别的思路。首先将提取出的已知雷达脉冲包络前沿波形进行统计,求出一条能代表雷达辐射源的"标准"前沿波形曲线,然后将被测雷达脉冲包络前沿波形与求出的"标准"前沿波形曲线进行相像程度比较,识别出雷达辐射源个体。理论分析和实验结果表明利用雷达脉冲包络前沿波形可以较好地进行辐射源个体识别。
A new Specific Emitter Identification (SEI) idea based on front edge waveform of the radar signal envelop is proposed. Firstly,a standard front edge waveform which standing a specific radar must be calculated by using many known front edge waveform of the specific radar signal; secondly,a front edge waveform of the unknown radar signal is compared with the standard front edge waveform,then the likeness coefficient between unknown waveform and standard waveform can be calculated. The speci, fic radar may he identified based on likeness coefficient. The result of experiment and theory analysis show that the method is effective.
