The book "Processing of SAR Data" offers a comprehensive introduction to the processing of synthetic aperture radar (SAR) data. It is aimed at students, professionals in the field of remote sensing, researchers, and designers of SAR systems. The content focuses on the generation of high-quality SAR images and presents new methods and algorithms for the interferometric processing of SAR data. Special attention is given to system and signal theory to explain how SAR images are created and how interferometric SAR images are produced. The book provides a detailed mathematical description of various focusing algorithms and guides readers from the basics of processing to the final geo-coded SAR data product. Algorithms are developed that take into account the effects of lateral geometry to correct issues such as foreshortening, shadowing, and overlap.
