基于载机信号重构的反辐射导弹检测技术

针对反辐射导弹的检测问题，主要是消除载机信号的干扰。提出一种基于栽机信号重构的反辐射导弹检测技术。首先，在频域估计出载机信号的多普勒频率以及幅度后，重构载机信号，并在分数阶Fourier域消除载机信号；最后结合载机信号和反辐射导弹信号在分数阶Fourier域的差别，有效地排除载机信号残余的干扰并检测出反辐射导弹。该方法不需要估计栽机信号的相位，因此简单易行。仿真证实，该方法可以有效地消除栽机信号干扰，并能检测出反辐射导弹。

ARM Detection Based on ARM Carrier Signal Restructuring

The anti radio missile(ARM) carrier signal is the main problem of the ARM detection.A method for detecting ARM based on ARM carrier signal reconstructing is proposed.Firstly,the amplitude and Doppler frequency of ARM carrier signal are estimated.Then,the ARM carrier signal is reconstructed and suppressed in fractional Fourier transform(FRFT) domain.Finally,according to the difference of ARM carrier signal and the ARM signal,the interference of the remainder of ARM carrier signal is excluded and the ARM sign...
