PULSE-PROPAGATION THROUGH A MOVING FLUID IN A STRATIFIED MEDIUM

The problem of an acoustic field generated by a point source moving wi th arbitrary velocity in a stratified medium in an underwater environm ent has been addressed by Lim and Ozard. The aim of this paper is to i nvestigate the field of a pulse emitted by a moving point source in th e presence of a moving fluid. The point source is excited by a rectang ular pulse with a finite non-zero rise a.nd decay time. For a slow-mov ing source the field is expressed entirely in terms of contemporary ti me. Finally, the physical interpretation of the result is discussed.
