“…The biggest and most significant of the purpose built SAS was originally built by Alliant under a DARPA contract then bought out by Techsystems then Hughes Aircraft and now owned by Raytheon Electronic Systems. However, since it was a military system, it produced few publications in the open literature [33,34]. Meanwhile in Europe under the umbrella of a European Union MAST programme, a low frequency ACID/SAMI sonar was producing interesting geophysical results.…”

This presentation gives an overview of the state-of-the-art in side-looking acoustic imaging using synthetic aperture techniques. It starts with the development of aperture synthesis, gives the historical background of synthetic aperture sonar (SAS), and then describes the salient differences between that and its electromagnetic equivalent; synthetic aperture radar (SAR). This paper takes a broad view of how SAS developed and where these developments occurred. We look at the past (with close attention paid to the patent literature), the present, as well as to hazard some guesses as to the future.
