Abstract:

Recent high-frequency acoustic ocean bottom scattering developments are described. A brief summary of experiments carried out in frequency range from 5 to 180 kHz during the 1980s is presented. These experiments were performed to identify specific scattering mechanisms leading to bottom backscattering, bottom forward loss, and sound penetration into the ocean subbottom. The capability to accurately predict acoustic scattering is addressed through model and data comparisons. Pertinent unresolved issues are discussed.
