Scattering by Spheres Buried in Sediment

Abstract

In this report the scattering of acoustic energy by an elastic sphere buried in sediment is examined. The geoacoustic model consists of two homogeneous fluid halfspaces separated by an intermediate layer. The source field is generated by either a point source or a vertical line array placed in the upper halfspace. The spherical shell is placed in the lower fluid halfspace and the scattered field is computed at an observation point placed at various locations in the upper halfspace.
