Abstract:

Bistatic acoustic scattering by a finite, water-filled, thin-walled cylindrical shell buried in the seabed is studied in the range 2–15ka. A model of the dynamics and azimuthal coherence of radiated elastic waves and periodic internal bounces is presented and validated on the basis of a 3D scattering model. Modelling and scattering analysis are applied to at-sea measurements of the response of a cylindrical shell, flush buried in sand and acquired on a horizontal line array. The model and data are found to be in reasonable agreement.
