Splet01. feb. 2001 · Various swath-sonar seafloor classification software tools have been popular among researchers, including academic ones e. g TexAn (Blondel, 1996;Blondel et al., 1998;Micallef et al., 2012) and... SpletIn this paper we examine the use of bathymetric sidescan sonar for automatic classification of seabed sediments. Bathymetric sidescan sonar, here implemented through a small receiver array, retains the advantage of sidescan in speed through illuminating large swaths, but also enables the data gathered to be located spatially.
