Sar backprojection
Webb13 aug. 2024 · Back-projection (BP) algorithm is an accurate and real-time SAR imaging method for arbitrary trajectory. The image quality depends on the accuracy of antenna … 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 …
