| 摘 要： | 提出了一种基于经验模式分解（EMD）方法和分数阶傅里叶变换（FRFT）来检测反辐射导弹（ARM）的新方法。首先利用EMD方法将ARM信号从雷达回波信号中分解出来，然后进行FRFT变换，最后设立适当的门限即可检测出ARM信号。仿真结果表明，该方法能够在ARM信噪比低达-16dB的情况下，准确地将ARM检测出来，实现实时告警。

| Abstract: | A new method for ARM detection based on EMD(Empirical Mode Decomposition) and FRFT(Fractional Fourier Transform) is presented.Firstly,the ARM signal is extracted from the radar echo signals by the method of EMD.Then the FRFT is processed.Lastly ARM can be detected by installing proper limit.The simulation results show that an accurate detection can be achieved even under-16dB ARM SNR,so that a reliable early warning can be given. |
