| 摘 要： | 双通道合成孔径雷达(SAR)和单航过的干涉合成孔径雷达(InSAR)有很强的抗干扰能力，固定的单站有源干扰机所发射的干扰信号到两通道的相位差是缓变的，可以被用来做干扰对消。该文提出利用双(多)干扰机对抗双通道干扰对消的方法，分析了双通道对消原理和双干扰机的信号特点，给出了双干扰机的干涉相位条件，讨论了干扰机干涉相位的估计方法。理论分析和仿真实验表明，该方法能有效减弱双通道雷达的抗干扰能力。

| Abstract: | Dual-channel SAR system and single-look InSAR system are characterized by strong anti-interference capability. In this paper, a countermeasure method against dual-channel cancellation is proposed based on two jammers, the principle of dual-channel cancellation is reviewed, the interference signals of two jammers are analyzed, the requirement of the interference phase of the two jammers and the estimation method are studied. Theoretical analysis and simulation experiment verify the effectiveness of the proposed method. |
