Seabottom characterization using multibeam echosounder angular backscatter; an application of the composite roughness theory

Seabottom characterization using multibeam echosounder angular backscatter; an application of the composite roughness theory

IEEE Transactions on Geoscience and Remote Sensing 38(5, Part 2): 2419-2422

Composite roughness theory is used to characterize Southern Ocean bottom backscatter (multibeam) data. Spectral parameters based on Helmholtz-Kirchhoff's theory [1] are determined from measured nearnormal incidence values. A splicing technique using Rayleigh-Rice theory [2] is employed beyond 20 degrees incidence angles. Estimated roughness parameters for six deep ocean areas correlate with geology.
