Abstract:

LONG-TERM GOALS To model the effects of volume heterogeneities, both discrete and continuous, in scattering from sand and mud sediments. A better understanding of the role of heterogeneities in seabed scattering could lead to improvements in sediment characterization using remote sensing techniques and a greater understanding of the mechanisms that affect mid-frequency reverberation.
