Principles of Underwater SoundThis revised third edition of the classic work on underwater sound provides a much-needed up-to-date summary of information and data on sonar and its applications. Unlike other books on the subject, it concentrates on the practical aspects of underwater sound, and offers engineers, operations analysts, naval officers, and other professionals in the field the immediately useful help they need for sonar problem solving. Its coverage is broad-ranging from the basic concepts of sound in the sea to making performance predictions in such applications as depth sounding, fish finding, and submarine detection. In addition, the book explores various areas of oceanography, detection theory, and other subjects where their processes and effects relate to underwater sound. |
