Abstract :
In this paper, traditional airborne SAR focusing algorithms are extended to the spatial configuration. The ω-k algorithm, chirp scaling algorithm with or without secondary range compression are expressed and developed for the spaceborne case with their limitations. A signal processing algorithm for hybrid strip-map/spotlight spaceborne SARs is also proposed
