Webbbackprojection is a processing algorithm for reconstructing images from data collected by synthetic aperture radar (SAR) systems. Factorized backprojection requires less computation than conventional time-domain backprojection with minimal loss in accuracy for straight-line motion. However, its implementation is not as straightforward as direct
Webb15 juli 2016 · Abstract: This paper puts forward a reverse backprojection algorithm for the moderately efficient generation of raw data of natural scenes acquired with general SAR geometries; in particular, we are interested in monostatic and bistatic geosynchronous (GSO) geometries. The backprojection algorithm has the advantage of being arbitrarily … WebbThe GPS data of an existing SAR platform were used for testing this mapping. Codes were developed for simulating the non-linear SAR signature of targets for a given set of flight path GPS data. We established the mathematical foundation and MATLAB codes for backprojection and wavefiont image formation algorithms for on a non-linear SAR …
