Abstract

Abstract

Compared with the Back Projection Algorithm (BPA), the interpolation load of the Fast Factorized Back Projection Algorithm (FFBPA) is released. However, the 2D interpolation in the image domain is essential for the FFBPA and the intensive computational burden limits its application in practice. This paper presents the geometric correction based FFBPA for the spotlight SAR imaging. In this algorithm, the sub-image registration is accomplished by the geometric correction method that the sub-image projection in the different coordinate systems and sub-image fusion are fulfilled by the shift in the range dimension and the rotation in the angle dimension. Thus the method avoids the individual interpolation and it is more efficient than the FFBPA. Simulation results validate its imaging performance and efficiency.
