This book provides a complete and modern treatment of sonar performance modeling. It demonstrates how sonar systems and methodology are used for a variety of sensing, communications and deterrence systems and by a number of industries and end-users.

Sonar performance modelling (SPM) is concerned with the prediction of quantitative measures of sonar performance, such as probability of detection. It is a multi-disciplinary subject, requiring knowledge and expertise in the disparate fields of underwater acoustics, acoustical oceanography, sonar signal processing and statistical detection theory. No books have been published on this subject, however, since the 3rd edition of Urick's classic work 25 years ago and so Dr Ainslie's book will fill a much-needed gap in the market. Currently, up-to-date information can only be found, in different forms and often with conflicting information, in various journals, conference and textbook publications.

Dr Michael Ainslie is eminently qualified to write this unique book. He has worked on sonar performance modeling problems since 1983. He has written many peer reviewed research articles and conference papers related to sonar performance modeling, making contributions in the fields of sound propagation and detection theory.

Covers for the first time in a single book the multiple disciplines involved in sonar performance modeling Makes the most up-to-date knowledge available to a wide audience. With rigorous and consistent mathematical notation, brings this complex and important subject to as wide a readership as possible Considers in depth each discipline of acoustics, oceanography, signal processing and detection theory Provides thorough and self-consistent definitions Gives derivations and worked examples for both expert and novice readers Illustrated with many worked examples at all levels using various modern SPM tools Includes supplementary material: sn.pub/extras

Klappentext

Dr Ainslie's book provides a long-awaited complete and modern treatment of sonar performance modelling (SPM). In this context, the word "sonar" is used in a broad sense, to mean any deliberate use of underwater sound, including by marine mammals. The acronym "SONAR" stands for "sound navigation and ranging", but this book demonstrates how sonar systems and methodology are used for a variety of sensing, communications and deterrence systems, and by a number of industries and end-users (military, offshore, fisheries, surveyors and oceanography).

The first three chapters provide background information and introduce the sonar equations. The author then lays the main foundations with separate chapters on acoustical oceanography, underwater acoustics, signal processing and statistical detection theory. These disparate disciplines are integrated expertly and authoritatively into a coherent whole, with as much detail as necessary added for more advanced applications of SPM. The book is illustrated with numerous worked examples, at both introductory and advanced levels, created using a variety of modern SPM tools.
