Opis

Written for students, remote sensing specialists, researchers and SAR system designers, Processing of SAR Data shows how to produce quality SAR images. In particular, this practical reference presents new methods and algorithms concerning the interferometric processing of SAR data with emphasis on system and signal theory, namely how SAR imagery is formed, how interferometry SAR images are created, and a detailed mathematical description of different focussing algorithms. Starting with the processing basics and progressing to the final geo-coded SAR data product, the book describes the complete processing steps in detail. Algorithms based on the effects of side-looking geometry are developed to correct foreshortening, shadowing and layover.

Written for students, remote sensing specialists, researchers and SAR system designers, this practical new reference shows you how to produce quality SAR images with respect to interferometrical applications using different algorithms. Processing of SAR Data shows how SAR imagery is formed, how interferometry SAR images are created, and gives you a detailed mathematical description of different focussing algorithms with special emphasis in interferomtery. The book describes in a comprehensive manner new methods and algorithms for interferometric processing of SAR data. It provides a general description with strong emphasis on system and signal theory. In this context a study is presented which derives a new, nonlinear, two-dimensional, space-variant SAR processing algorithm. A comparison is presented of different SAR focussing algorithms by making use of a uniform starting point, the two-dimensional point target spectrum. With regard to subpixel accuracy, a method is introduced for the co-registration process. Based on the geometrical effects of the side looking geometry, computationally efficient algorithms are developed to correct foreshortening, shadowing and layover. Based on a method of automatically generating reference heights, the outfinal SAR data product is geocoded.
