Joint autofocus and registration for video-SAR by using sub-aperture point cloud

Joint autofocus and registration for video-SAR by using sub-aperture point cloud

Due to the existence of antenna phase center (APC) error, drift occurs on the sequence of images acquired by video-SAR back projection (BP) algorithm with respect to a fixed coordinate system. Theoretical analysis shows that the drift is directly related to APC errors. Thus, we propose a novel joint...
