Abstract
Composite roughness theory is used to characterize Southern Ocean bottom ba ckscatter (multibeam) data. Spectral parameters based on Helmholtz-Kirchhof f's theory ill are determined From measured near-normal incidence values. A splicing technique using Rayleigh-Rice theory [2] is employed beyond 20 de grees incidence angles. Estimated roughness parameters for six deep ocean a reas correlate with geology.
