摘要： 针对多通道合成孔径雷达-地面动目标显示(SAR-GMTI)二维余弦调相散射波干扰展开深入研究.在传统SAR散射波干扰基础上，阐述了二维余弦调相散射波干扰原理，以双通道偏移相位中心天线(DPCA)技术为例分析了其对多通道SAR-GMTI的对抗性能，并以强散射性诱饵为散射目标进行了仿真实验和应用分析.理论分析和仿真实验表明：该方法对SAR-GMTI可产生携带真实目标散射信息的二维“网状”多假目标，并可通过合理配置干扰机和诱饵目标的数量和位置灵活控制干扰目标分布，通过诱饵目标运动实现更加逼真的动目标干扰效果.

Abstract: Two-dimension (2-D) cosinusoidal phase-modulated scatter-wave jamming for multi-channel synthetic aperture radar-ground moving target indication (SAR-GMTI) is studied. First, based on the traditional scatter-wave jamming for SAR, 2-D cosinusoidal phase-modulated scatter-wave jamming theory is introduced. Then, the countering performance against SAR-GMTI is analyzed by using the dual-channel displaced phase center antenna (DPCA) technique. Finally, strong scattering baits are set as scattering targets to carry out computer simulation and application analysis. The research result shows that the jamming method can produce 2-D netted multi-false targets with real targets scattering information for multi-channel SAR-GMTI. In practical application, the distribution of jamming targets can be flexibly controlled by the rational allocation of jammers and bait targets, and the vivid moving false target jamming performance can be realized by the baits’ motion.
Key words: synthetic aperture radar-ground moving target indication(SAR-GMTI), 2-D cosinusoidal phase-modulated, scatter-wave jamming, displaced phase center antenna, bait target
