Principles and Applications (Second Edition)

Xavier Lurton

AN INTRODUCTION TO UNDERWATER ACOUSTICS: Principles and Applications (Second Edition) An Introduction to Underwater Acoustics is at the same time a clear and concise text and a practical handbook. This updated and revised new edition provides an extended overview of current underwater acoustics, describing the basic physical phenomena governing underwater acoustical waves, propagation, reflection, target scattering and noise. It covers the general features of sonar systems, transducers and arrays, signal processing and performance evaluation. Its value for students and teachers is maximized by a new section containing well-validated exercises and problems, with solutions, and a substantial appendix adds useful complementary information to the various topics addressed in the chapters.

There is a wealth of new materials, including

and much more.
