The SARbackprojection MATLAB code is an implementation of the BackProjection algorithm. The code takes the raw data in the form of complex-valued signals and uses Fourier transforms to convert it into time-domain data. The data is then processed using mathematical calculations to create the final...
On the other hand, time-domain back-projection (BP) SAR imaging approaches are considered as optimal solutions to performing precise image focusing and MOCO. Among current BP algorithms, the fast factorized back-projection (FFBP) algorithm is one of the most essential representatives that achieve ...
First, based on the imaging geometry of BFSAR, the principle and implementation of Back Projection(BP) algorithm are presented. Then, the phase error in FFBP algorithm is analyzed, and the formula of the phase error in bistatic forward looking SAR is derived. The implementation of FFBP ...
We introduce and discuss a parallel SAR backprojection algorithm using a Non-Uniform FFT (NUFFT) routine implemented on a GPU in CUDA language. The details of a convenient GPU implementation of the NUFFT-based SAR backprojection algorithm, amenable to further generalizations to a multi-GPU architec...

Experiences with mapping the SAR Backprojection AlgorithmVasilache, Nicolas
The Back-Projection Algorithm (BPA) is a time-domain-matched filtering technique to form synthetic aperture radar (SAR) images. To produce high-quality BPA images, precise navigation data for the radar platform must be known. Errors in position, velocity, or attitude result in improperly formed ...
