Shadows by IXSEA: An Example of a Sonar Using the Latest Technologies in Acoustics, Positioning, Informatics, and Web Techniques

This study provides a new system for imaging the sea ground using the newest technologies in acoustics, sonar theory, positioning, informatics, and web techniques. The new side scan sonar called SHADOWS is the first commercially available sonar using the Synthetic Aperture Theory. This principle, introduced in radar since the 1970s, consists of rebuilding a long antenna by adding different contributions along time.
