Identification of the size, proportions and location of a soft body of revolution in a shallow-water waveguide

A made-matching method is first presented for solving a forward 3D problem of the scattering of an acoustic wave from a body of revolution located on the vertical axis of a cylindrical reference system within a horizontal sha llow-water waveguide. Results provided by the above-mentioned method are th en used to determine the sound field in such a waveguide and to study the i nverse problem of determining the size, proportions and location of an embe dded object. The difficulties that can be encountered when solving this inv erse problem are analysed and a strategy is proposed for overcoming some of them.
