Acoustical Boundary Location Through Texture Analysis of Multibeam Bathymetric Sonar Data

Abstract

Texture analysis is performed on multibeam sonar signal returns discriminated angularly by beamforming. A collection of fourteen texture features are computed via co-occurrence matrices and data reduction is then performed using a principal components transformation. Acoustical boundaries (boundaries between regions with homogeneous acoustical properties) are evident from the features. Results indicate that seafloor bottom characteristics can be extracted from these texture features.... Hydrography, Bathymetry, Optical properties, Remote sensing, Reverberation.
