On the problem of determining the position of a source of internal waves (Q6563544)

In the case when a body moves in a continuously stratified fluid at a constant speed, the wave field moves along with the body and forms a field attached internal waves. The incident flow is usually assumed to be constant, and nonstationary waves generated at the initial stage of motion are neglected. In this case, the body is simulated by point-mass sources and the wave field can be computed using the Green's function method, followed by the use of asymptotic expansions based on the stationary phase method. The author investigates the inverse problem of determining the source position when the wave field is known.
