Blondel, P. * Seafloor surveying with acoustic remote sensing has become a powerful tool for researchers and professionals seeking knowledge about the structure and behavior of the seafloor. Sidescan sonar is proving to be the preeminent technique, but its data is often difficult to interpret due to the physics of acoustic remote sensing, and to the varied geological processes at play. * This book covers all the fundamentals of sidescan sonar, and goes on to explain how to interpret sidescan sonar imagery and bathymetry. It fully explores the most recent advances in sonar technology as well as new understanding of marine structures, and provides deep insights for interpretation and decision-making. Broadly expanded and updated from the previous 1997 "Handbook of Seafloor Sonar Imagery", this handbook is indispensable to oceanographers, resource exploiters, telecommunications engineers, and marine researchers of all kinds. * Makarov, D. et al. World Scientific Publishing Co.Pte. Ltd. 2009.12 * A systematic study of chaotic ray dynamics in underwater acoustic waveguides began in the mid-1990s when it was realized that this factor plays a crucial role in long-range sound propagation in the ocean. The phenomenon of ray chaos and its manifestation at a finite wavelength - wave chaos - have been investigated by combining methods from the theory of wave propagation and the theory of dynamical and quantum chaos. * David H. et al. ed.

That is why this valuable reference provides a complete survey of methods for computational acoustics, namely FEM and BEM. It demonstrates that both methods can be effectively used in the complementary cases. * |
