| 摘 要： | 以简单脉冲、线性调频、二项编码和频率编码信号为例,通过提取信号的延时相关频谱特征,对雷达信号的脉内调制特征进行了分析。在分析和提取了信号的延时相关频谱结构特征后,提出了一种基于延时相关频谱进行调制方式识别方法。仿真和试验结果表明:在低信噪比情况下,是一种较好的雷达脉内调制方式识别方法。

| Abstract: | Taking single pulse(SP)signal,linear frequency modulation(LFM)signal,BPSK signal and FSK signal as examples,several kinds of intra-pulse modulation characteristics of radar signal are analyzed and illustrated through extracting the delay-correlated spectrum signature of signal.The structure of delay-correlated spectrum is analyzed,based on which a method of modulation identification is proposed.The simulations and experiments show that the method is efficient under low signal to noise rate(SNR). |
