摘要：
Composite roughness theory is used to characterize Southern Ocean bottom backscatter (multibeam) data. Spectral parameters based on Helmholtz-Kirchhoff's theory ill are determined From measured near-normal 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.
