Time and Frequency Domain Solutions for Vertically Incident Waves in Multilayered Absorptive Media with an Application to Source Depth Determination

Abstract

Solutions of the ray propagation equation are obtained for various boundary conditions, assuming vertical incidence in plane, parallel, equal- travel-time layers. The solutions are examined in both the time and frequency domains and certain properties derived. A complete discussion of frequency- domain synthesis techniques is given in connection with a treatment of the absorption problem. FORTRAN programs are given which compute any of the solutions in either the frequency or time domains, with or without absorption. The theory and programs are applied to the problem of source depth determination, and it is shown that the method of pP spectral nulls is somewhat unreliable. (Author)
