Fast back projection code

WebWith back-projection, the imaging process can be very time-consuming; therefore, in this effort, we have presented a fast back-projection algorithm that provides significant computational savings with only modest loss in image quality. This paper introduces the back-projection algorithm and two fast back-projection algorithms. WebDec 19, 2024 · An Efficient Backprojection Algorithm Based on Spectral Splicing Abstract: This paper introduces a fast back projection synthetic aperture radar imaging algorithm based on wavenumber spectrum splicing. The traditional algorithm establishes the polar coordinate system with the center of the sub aperture as the origin.
