摘　　要： 针对单部干扰站难以对合成孔径雷达双通道对消系统实施有效干扰的问题,提出了合成孔径雷达双通道对消的多站干扰方法。该方法利用多部干扰站实施分布式协同干扰,使SAR系统无法通过估计每个采样时刻的补偿相位对双通道的干扰信号进行对消,并给出了使双通道对消系统失效的相位条件和多干扰站沿方位向的部署方案。仿真实验表明,该方法可有效破坏SAR双通道干扰对消的性能,显著增强直达波干扰和散射波干扰对双通道SAR系统的干扰效果。 SAR dual-channel cancellation technique can suppress the jamming signal of single jammer.An jamming method of multi-jammers against SAR dual-channel cancellation system was proposed.The proposed method used multi-jammers to implement distributed cooperative jamming,thus the SAR system could not estimate the compensation phase of each sampling time,which made SAR dual-channel cancellation technique invalid.Then,phase condition and jammer configuration scheme that made the dual-channel cancellation invalid were discussed.The simulation results showed that the method could effectively destroyed the SAR dual-channel cancellation system,and enhanced the jamming performance of direct wave and scatter-wave against dual-channel SAR system.
