projection algorithm‐based GEO SARgeosynchronous earth orbit synthetic aperture radarGeosynchronous earth orbit synthetic aperture radar (GEO SAR) has the advantages of short revisit period and wide observation range. However, compared with low earth orbit SAR (LEO SAR), GEO SAR has the distinct ...
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...

Actually, the imaging area of each sub-aperture is usually larger than this circle area, and because of the beam control error and the attitude measurement error of the SAR, the imaging area setting by the BP algorithm needs some redundancy. However, if the BP imaging area is too large, ...
In this paper, a fast back-projection (BP) synthetic aperture radar (SAR) imaging algorithm based on wavenumber spectrum fusion is proposed for high maneuvering platforms with high squint angles and high dive angles. When the platforms have nonlinear trajectory errors, the trajectory errors will int...
