“…An alternative is the GF technique proposed by Anderson [3], in which image formation is described by superimposing elementary GFs. Our method is analogous to, but differs from [3] in three major points.…”

In this paper, we describe a space-time analysis for synthetic aperture sonar (SAS) employing Green's functions (GF), and show that it's basically an inverse problem. Iterative focusing is proposed based on this viewpoint. In order to mitigate difficulties of slow convergence and computational costs inherent in iterative methods (IM), an acceleration technique is used. Applications to SAS imaging is demonstrated through reconstructions from simulated data, with emphasis on high resolution and iimage quality.
