A Model for High Frequency Acoustic Backscatter from Gassy Sediments at Shallow Grazing Angles

Friday, March 5, 1993 4:00 p.m. Frank A. Boyle Applied Research Laboratories Recent experimental backscatter data suggests a volume scattering mechanism involving trapped gas bubbles. A model for shallow grazing angle high frequency acoustic backscatter from sediment is developed. The model begins with a pore distribution function, obtained from measurements of the grain size distribution…
