Webb6 dec. 2024 · Compared with the original backprojection (BP) algorithm, the fast factorized BP algorithm accelerates enormously. As it is known to all, 2-D image interpolations are always utilized to raise the accuracy, yet leadings to the tradeoff with the efficiency. In this paper, a novel factorized BP algorithm based on Cartesian coordinate without … WebbIntroduction The backprojection (BP) or so called Beam Formation (BF) Imaging Algorithm is designed in this project. The BP algorithm firstly is stated in the CT area, then the same idea is used in the synthetic aperture radar (SAR).

For the parallelization of the backprojection process, a processing data unit is defined as the phase history data or range profile data from partial synthetic-apertures divided from the full resolution target data.
Webb15 nov. 2024 · One of the uses of digital spotlighting is to mitigate the computational burden of back-projection of the SAR VPH to image the scene. Since back-projection is an O(N 3) algorithm, it does not scale, so digital spotlighting is a way to break up the phase history into computationally manageable sections for imaging via back-projection.. …
WebbSynthetic Aperture Radar (SAR) is a technology used to form high-resolution imagery1,2. The fundamental idea is to synthesize a very long antenna, put into practice by recording radar echoes along a track and combining these coherently.
