Sonar for Practising Engineersby Ashley Waite
Synopses & Reviews
The aims of the book - written by a practising engineer for practising engineers - are to provide an understanding of the basic principles of sonar and, to develop formulae and "rules of thumb" for sonar design and performance analysis. Ashley Waite uses his long experience in the design, trials and performance analysis of sonar systems to provide practical guidance and solutions to problems encountered by sonar engineers and technicians.
The books divides into the following parts:
* Equipment parameters: the motion of sound in an elastic medium; definitions of sound intensity and source level; the use of projector arrays to increase the source level; the use of hydrophone arrays to improve the signal to noise ratio of a wanted sound.
* The propagation of sound in the sea and the backgrounds to detection: spreading and absorption losses; propagation modes and simple modelling; noise and reverberation; the sonar equations
* Practical sonar systems: passive and active sonar systems; passive broadband, narrowband, intercept and communications (as a special case of intercept) sonars; active sonars for the detection of submarines, mines and torpedoes.
Sonar for Practising Engineers, third edition, covers all aspects of sonar systems and has extensive worked examples. No prior knowledge of sonar is assumed and the physical principles and mathematics will be readily understood by engineers, technicians and students of underwater acoustics. New to this edition, are end-of-chapter exercises and solutions for self assessment and training.

Written by an engineer for engineers, this book takes an engineering approach rather than a physics/math one. It provides an understanding of the basic principles of Sonar and develops the formulae and rules of thumb for sonar design and performance analysis.
Das erste Buch für Ingenieure, das sich ausschließlich Sonaren und Sonartechnologien widmet! Der Autor verfügt über vierzig Jahre Erfahrung auf diesem Gebiet und verfolgt einen weniger physikalisch-mathematischen als vielmehr praxisnahen Ansatz. Ausgehend von der Erklärung grundlegender Arbeitsprinzipien des Sonars werden Formalismen und Faustregeln für den Entwurf und die Leistungsanalyse erarbeitet. Besprochen werden u.a. Anordnungen zur Richtungsbündelung, Rauschquellen sowie Anwendungen in der Kommunikationstechnik.
The first book exclusively on sonar and sonar technology. Written by an engineer (with over 40 years of experience in the field) for engineers. Taking an engineering approach rather than a physics/math one it provides an understanding of the basic principles of sonar and develops the formulae and "rules of thumb" for sonar design and performance analysis.
About the Author
ASHLEY WAITE retired from the UK Ministry of Defence in 1990 after 40 years of Underwater Warfare Research at Portland. He then joined Thomson Marconi Sonar (now Thales Underwater Systems Limited) as a Consultant for a further 10 years. He still maintains an involvement with sonar in a freelance capacity.
