Description: In the proposed algorithm, the range-independent de-rotation operation is employed to overcome the spectrum aliasing problem, and the signal properties after de-rotation are derived in detail. Moreover, a modified range-dependent deramp function is proposed to accommodate the time shift, and the chirp-z transform is utilized for correcting geometry distortions caused by the range-dependent deramp operation. Furthermore, range scaling and azimuth scaling are performed, providing the same pixel sampling interval for all sub-swath images in both range and azimuth dimensions respectively, which avoids interpolation for the sub-swath image
