How Mapping Sonars Work

MB-System supports data from multibeam, interferometry, sidescan, and subbottom profiler sonars. Much has been written to explain how these sonars work and are used. This section provides links to such documents that we have permission to redistribute or are available on other sites. The MB-System team and its supporting institutions and funding agencies make no claim regarding the accuracy or usefulness of these documents.
