考虑到敌方合成孔径雷达的运动误差，提出了一种新的实时欺骗干扰方法。该方法首先对欺骗图像进行预处理，然后对接收到的信号进行卷积运算并发送信号，这样可以有效地模拟出合成孔径雷达平台到干扰设备的距离，回波中包含运动信息，经过运动补偿和SAR成像运算后，可以得到更逼真的图像。该方法提出了一种基于两步处理的欺骗场景信号快速生成算法，保证了信号的实时生成。仿真和实验数据证明了该方法的有效性。
Considering the motion error of the enemy SAR,this paper proposes a novel realtime approach of deception-jamming.Via quick algorithm,this method pretreats the deception picture first,and then does the convolution operation with the received signal and transmits the signal.In this way,the distance between SAR platform and jamming equipment can be simulated effectively,and the echos contain the motion information.After motion compensation and SAR imaging operation,a more lifelike image can be obtained.This method proposes a quick algorithm of deceptive scene signal generation based on two-step processing,which ensures realtime generation of the signal.Simulation and experimental data have proved the validity of the approach.
