Modelling of scattering by objects on the seabed

Thumbnail
Abstract
This paper describes some of the theory and implementation issues of modeling the backscattered
 
energy from cylindrical or spherical objects lying on the seabed. The model utilizes a single-scatter
 
approximation. The effects of various parameters such as grazing angle of the incident energy,
 
receiver/scatterer geometry and the bottom halfspace geoacoustic parameters are investigated
 
numerically. The paper is concluded with a comparison of modelled time series with experimental scattering data obtained for a steel-shelled cylinder and a solid aluminum sphere lying on a sandy seabed.
