"Underwater Acoustics and Signal Processing" ed. by Leif Bjørnø

These Proceedings should form an advanced textbook in the field of underwater Acoustics and Signal Processing. Audience - the students, are scientists who already have specialized in the field or who possess an advanced general background.

This issue followed a tutorial format, forming a high-level teaching activity with the purpose of familiarizing advanced postgraduate students and postdoctoral scientists and engineers with the fundamental theories and up-to-date applications of present knowledge, while most recent research results were presented in a limited number of advanced research papers.

The general line in the topics presented at this NATO ASI has been to give an extensive and thorough account of underwater sound generation, underwater sound propagation, underwater sound reception, including transducers, and the processing of underwater sound signals.
