World Scientific Publishing Co. Pte. Ltd., USA, 2001. – 389 p. – ISBN: 9812811958, 9789812811950This volume comprises chapters of Propagation, Ocean Acoustics, and Scattering, and contains a substantial amount of material on acoustic wave propagation in fluids bounded by elastic media, in waveguides and in particular, in the ocean as influenced by the (elastic) seabed.
This book offers a collection of contributions from these research centres that represent the present state-of-the-art in the study of acoustic elastic interaction, being on the cutting edge of these investigations. This includes the description of acoustic scattering from submerged elastic objects and shells by the resonance scattering theory of Flax, Dragonette and Uberall, and the interaction of these phenomena in terms of interface waves. It also includes the use of this theory for the purpose of inverse scattering, i.e. the determination of the scattered objects properties from the received acoustic backscattered signals.
A comprehensive picture of complex phenomena and other aspects is presented in the book by researchers that are experts in each of these domains, giving up-to-date accounts of the field in all these aspects.
In this vein, the set of first six chapters (Chapter 1 through 6) deals with sound propagation in wave guides, acoustic reflection from the ocean floor, and models for ocean sound propagation in both deep and shallow oceans. Resumes of recent developments in these areas are presented, as well as original work including sophisticated mathematical approaches.
The general topics represented here include both propagation and ocean acoustics, as well as the field of target scattering already opened up in the first part of this volume.
