Method for image generation for synthetic aperture radar sensors, involves carrying out range compression and global walk correction, where subsequent dechirp function and forward Fourier transformation are performed

摘要

The method involves carrying out range compression and global walk correction, where a subsequent dechirp function and a forward Fourier transformation are performed by a symmetrical azimuth shift and a subsequent inverse Fourier transform respectively. The correction of a non-square range walk, a change in walk curvature and a residual Doppler phase progression are carried out in a subsequent manner.
