METHODS AND ALGORITHMS FOR AMBIGUITIES SUPPRESSION IN SPACE-BASED SAR

Space-based synthetic aperture radars (SAR) are widely used for remote sensing of the Earth. One of the problems of such systems is the presence of range and azimuth ambiguities which significantly affect the quality of radar images. A large number of techniques and approaches are known that have been developed to reduce ambiguities. At the same time, such variety of methods requires their generalization and analysis. The paper provides review and classification of methods and algorithms for range and azimuth ambiguities suppression in space-based SAR.
