Experiences with mapping the SAR Backprojection AlgorithmVasilache, Nicolas
SAR (synthetic aperture radar) is a remote sensing technique that uses radar to create high-resolution images of the earth's surface. The BackProjection algorithm is a commonly used method to generate SAR images. It works by processing the raw data obtained from the radar into a two-...
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 ...
A key requirement of the filtered back projection reconstruction algorithm typically used by CT is for the set of 2-D images to represent a full 360[degrees] rotation of the object relative to the source and detector. 3-D X-Ray inspection looks into the void n In the space of four eveni...
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...
