The Application of SSC for RFI Suppression in SLC Images of Sentinel-1 IW Mode

通过对 Sentinel-1 IW 模式下产生 SLC 数据的成像算法的理论分析，发现方位后处理中的相位补偿步骤破坏了频谱的对称性，不能满足 SSC 方法应用的基础，导致 RFI 抑制性能较差。在此基础上，我们首先对受 RFI 污染的 SLC 图像进行反相位补偿，恢复频谱对称性。第二步是子带分割和子图像能量对消。这种方法在抑制 RFI 的同时有效地保护了有用的信号，对 Sentinel-1 SLC 图像的进一步应用具有重要意义。仿真和实测实验验证了该方法的有效性。[pdf, SCI, EI, IF=4.8003, CAS-G3, JCR-Q1]
