Abstract:

OASES uses wavenumber integration to solve for the backscattered pressure caused by sound speed and density inhomogeneity scatterers in the sediment SCARAB uses a ray path technique to find the backscattered intensity. This report compares the two models for a variety of sediment backscattering scenarios and identifies situations where the accuracy of SCARAB is compromised.
