ABSTRACT: Factorized
backprojection is a processing algorithm for reconstructing images from data
collected by synthetic aperture radar (SAR) systems. Factorized backprojection
requires less computation than conventional time-domain backprojection with minimal loss in accuracy for straight-line
motion. However, its implementation is not as straightforward as direct
backprojection. This paper provides a new, easily parallelizable formulation of
factorized backprojection designed for stripmap SAR data
that includes a method of implementing an azimuth window as part of the
factorized backprojection algorithm. We compare the performance of windowed
factorized backprojection to direct backprojection for simulated and actual SAR
data.
