A unified model for seabed volume and roughness scattering

Thumbnail
Abstract
Seabed scattering is considered taking into account perturbations of different type: volume inhomogeneities and roughness of the interfaces. A description is given in terms of plane waves. The first-order perturbation solution is presented for the scattering amplitude and scattering cross-section. Cross-correlation matrices between the roughness of different interfaces and between the volume fluctuations of different parameters are involved. The model is generalized to the case of the fluid sediment placed over an arbitrary basement having its own reflection and scattering properties.
