摘　　要：针对单部干扰机生成虚假(动)目标干扰方法在对抗具有地面运动目标指示(GMTI)功能的合成孔径雷达(SAR)或对抗干涉合成孔径雷达(InSAR)时存在的固有缺陷,提出了一种基于双干扰机协同的SAR-GMTI/InSAR有源欺骗干扰方法。该方法揭示了虚假(动)目标与真实目标在SAR/InSAR图像域中的本质区别,在此基础上,给出了统一的干扰实施步骤,其方法通用性强。研究表明:利用2部干扰机的空间自由度,该方法不仅能够克服单部干扰机对抗SAR-GMTI/InSAR时存在的不足,而且能使现有利用单部干扰机生成虚假(动)目标时的固有缺陷的抗干扰方法失效。理论分析和仿真实验结果验证了该方法的可行性。Aiming at the inherent defects of the jamming method of generating false targets by a single jammer against SAR with GMTI function or InSAR,a jamming method of SAR-GMTI/InSAR active deception based on dual-jammer cooperation is proposed.This method revealed the essential difference between false target and real target in SAR/InSAR image domain.On this basis,a unified jamming implementation step is given in detail,which has a strong universality.The research shows that the spatial freedom degrees usage of two jammers,the proposed method can not only overcome the shortcomings of single jammer against SAR-GMTI/InSAR,but also invalidate the existing anti-jamming methods that use the defects of single jammer to generate false targets.Theoretical analysis and simulation results verify the feasibility of the proposed method.
