基于脉冲包络前沿高阶矩特征的辐射源个体识别

Specific Emitter Identification Based on Higher Order Moment of the Envelope′s Front Edge

雷达脉冲包络分析是雷达辐射源识别的常规方法,但常规的包络识别方法很难适应实际需要,无法有效地对雷达辐射源信号进行分类识别。提出了以脉冲包络前沿波形的高阶矩特征作为辐射源的"指纹"特征,进行雷达辐射源个体识别的思路。利用脉冲包络前沿波形的高阶矩特征受高斯噪声影响较小的特点,提高了辐射源个体特征参数的有效性。理论分析和实验结果表明利用雷达脉冲包络前沿波形的高阶矩特征可以较好地进行辐射源个体识别。

The analysis of radar signals envelope is a traditional method to identify radar signals.The traditional method and theory of recognition can hardly satisfy practical requirement and can′t effectively recognize for radar signals.A new specific emitter identification（SEI） idea based on higher order moment feature of the envelope′s front edge waveform is proposed.The higher order moment feature of the envelope＇s front edge waveform is an effective individual character,because of Gauss noise′s lesser effect.The results of experiment and theory analysis show that the higher order moment feature of the envelope＇s front edge waveform is feasible using in SEI.
