Прямые и обратные задачи акустического зондирования дна водоемов

Acoustic waves in complex media formed by a horizontal water layer on the boundary of an elastic half-space are considered. The waves are generated by a point source on a free water surface. A direct initial-boundary value problem is formulated for the corresponding partial differential equations. If the mechanical parameters of the elastic medium depend only on depth, the inverse dynamic problem of finding the acoustic impedance of the medium is solved.
