Abstract

When bodies move in a continuously stratified fluid, the steady wave field moves along with the body and form a field of so-called associated internal waves. The flow incident on the body is usually assumed to be constant; non-stationary waves generated at the initial stage of motion are neglected. In this case, the body is modeled by point mass sources, and the wave field is found using the Green’s function method, followed by the use of asymptotic expansions based on the stationary phase method [1]. The inverse problem of determining the position of the source is solved from the wave field.
