Opis książki

Written in tutorial style, this textbook discusses the fundamental topics of modern day Sonar Systems Engineering for the analysis and design of both active and passive sonar systems. Included are basic signal design for active sonar systems and understanding underwater acoustic communication signals. Mathematical theory is provided, plus practical design and analysis equations for both passive and active sonar systems. Practical homework problems are included at the end of each chapter and a solutions manual and lecture slides for each chapter are available for adopting professors. "I have taught underwater acoustic courses for years and I find that Professor Ziomek's style used in his other books is well liked by students. This new book continues that style and I'm certain that my students will find it an effective learning tool. " -James H. Miller, University of Rhode Island, USA "The book is very well written and it is very rigorously presented. I believe this will be a perfect reference for students and practitioners." - Alessio Balleri, Cranfield University, United Kingdom
