摘要

Scattering from submerged bounded objects has been treated extensively in the frequency domain. For elastic targets, resonance scattering is of a particular interest and has proven to be rich in phenomena that can be described for the most part using resonance scattering theory (RST) for the frequency domain problem. The time domain solution has not been developed within the context of such a theory and appears somewhat more elusive with regard to ease of interpretation when compared to the frequency domain case. In this work we propose a development that is based on the frequency domain RST and offers a tool for analysis and a contextual basis for the interpretation of at least some of the phenomena that appear in time domain calculations and theory. Keywords: Acoustic scattering; Shallow water, Waveguide propagation, Reprints. (jhd)
