Bottom bistatic scattering: experimental results and model comparison for a carbonate sediment
Williams, Kevin L.; Jackson, Darrell R. (NATO. SACLANTCEN, 1997)Bistatic scattering measurements were carried out under the Coastal Benthic Boundary Layer (CBBL) program. The results presented here are for a carbonate sand-silt-clay, and the data were collected in Februar) 1995 near ... -
Modeling of subcritical penetration into sediments due to interface roughness
Thorsos, Eric I.; Jackson, Darrell R.; Moe, John E.; Wiliams, Kevin L. (NATO. SACLANTCEN, 1997)Recent experimental results reveal acoustic penetration into sandy sediments at grazing angles below the critical angle. We have been investigating a mechanism for subcritical penetration based on scattering at a rough ... -
Temporal fluctuation of backscattered field due to bioturbatioon in marine sediments
Jones, Christopher D.; Jackson, Darrell R. (NATO. SACLANTCEN, 1997)Biological activity in marine sediments creates a time-varying, randomly fluctuating medium. A bio-diffusive model is proposed for predicting the temporal and spatial spectrum of sediment density fluctuations. Perturbation ...
