Abstract
This paper describes a modified polar format algorithm for SAR
imageformation processing. The algorithm focuses raw data assuming a
spherical reference surface (ground surface), and, unlike standard
polar format algorithms, it assumes spherical rather than planar
signal wavefronts. The algorithm, or some variant of it based on the
same geometry, is therefore more suitable than the standard polar
format algorithm in spaceborne applications for which there is
significant curvature of the platform flight track and/or curvature of
the Earth surface. The algorithm is described here in the context of
spotlightmode data acquisition.
