Abstract

Basic idea of this work is the realization of a digital Synthetic Aperture Radar (SAR) processor which can process the SIR-C/X-SAR raw data. Presented processor is based on fast Fourier transform codes and on the analytical evaluation, via stationary phase method, of the SAR system transfer function (STF). STF is shown to be intrisically two-dimensional and range dependent; a new solution for compensation of the SAR system transfer function range dependence is given. It is also presented a modification of the basic algorithm in order to extend the processing approach to airborne data. A number of experiments confirms theoretical analysis.
