Abstract

Abstract

Fast Factorized Back-Projection (FFBP) is originally developed for Ultra-WideBand (UWB) Synthetic Aperture Radar (SAR), and it shows great success for spotlight SAR signal processing. However, its implementation is not straightforward for stripmap SAR due to the limitation of integration aperture and angular upsampling. To investigate the applicability of FFBP to stripmap SAR, this paper describes a reasonable implementation of overlapped-image method based on integration aperture and angular wavenumber bandwidth. This approach retains high efficiency of the original FFBP. Finally, the simulated squinted SAR data are utilized to verify the effectiveness of the proposed method.
