A deceptive jamming method against terrain observation by progressive scans synthetic aperture radar (TOPSAR) that considers the effect of the changing relative position between a jammer and a TOPSAR platform is presented. The method can generate flexible false targets with varying Doppler centroids. The jamming problem is decomposed into simpler subproblems of the same type, according to the relative position between the jammer and the satellite. The partial deceptive jamming modulation function can be pregenerated before the radar parameter reconnaissance. The partitioned scheme produces multiple deceptive jamming batches in parallel on the TOPSAR image to protect large regions of interest.

一种针对TOPSAR的分区欺骗干扰方法

提出了一种考虑干扰机与TOPSAR平台相对位置变化影响的逐行扫描合成孔径雷达(TOPSAR)对地形观测的欺骗性干扰方法。该方法可以生成具有不同多普勒质心的灵活假目标。根据干扰机和卫星之间的相对位置，干扰问题被分解为相同类型的更简单的子问题。部分欺骗性干扰调制函数可以在雷达参数侦察之前预先生成。分区方案在 TOPSAR 图像上并行产生多个欺骗性干扰批次，以保护大的感兴趣区域。
