双站合成孔径雷达有源欺骗干扰方法研究

Active deception jamming to BiSAR

针对双站SAR系统中欺骗干扰信号的形式和产生方法,提出了对双站SAR进行有源欺骗干扰的方法。该方法首先根据事先确定的双站SAR信号频率,得出干扰机的响应函数,将此函数与接收到的双站SAR信号在频域相乘,再变换到时域,最后直接向双站SAR系统的接收平台的方向发射。

Aiming at the signal form and the generation method of the active deception jamming for BiSAR system, the method of active deception jamming is proposed. This method need to ascertain the signal frequency of the bistatic SAR ahead of time,which can provide responding function of the jammer. This function is multi plied by the signal of the bistatic SAR in the area of frequency, then transformed to the area of time and transmitted to the receiver of bistatic SAR system directly in the end.
