Abstract :
We investigate the space-variance of the synthetic aperture radar (SAR) transfer function due to focus depth variation and Earth rotation effect. We introduce a procedure for efficient space-variance compensation which is based on the use of a nonstandard Fourier transform (FT). A number of experiments confirming theoretical results are presented.<>
