Summary:
The key essentials and systems issues of designing practical sonar systems are highlighted in this course. The course provides a step-by-step guide to understanding and designing modern sonar systems. It addresses the fundamental concepts applicable to sonar systems including sound propagation, design and use of transducers, beamforming, signal processing and displays. Design examples of surface ship active/passive sonar, variable depth sonar, and mine hunting and localization sonars are presented to illustrate the current state of the art in sonar. Performance prediction and analysis will be discussed. You will acquire the knowledge, perspective, and practical skills needed to understand modern sonar technology.
The course is valuable to government and industry engineers, managers, and others who need a practical working knowledge of the theory and applications of modern sonar. You'll benefit from the more than 50 years of combined hands-on experience of the instructors and their case studies. The course examines the design tradeoffs and potential performance of modern sonar. Current issues, such as shallow water performance, and future trends are discussed. A complete set of notes & Principles of Underwater Sound by Robert Urick (McGraw-Hill) textbook will be supplied to all attendees.
Instructors:
Mark A. Chramiec retired from Raytheon's Submarine Signal Division after 34 years of developing, testing and improving various types of military and oceanographic sonars for the U.S. and numerous international navies. These included active and passive submarine and surface ship ASW sonars, bathymetric and sub-bottom-profiling sonars, sonars used for remote control of offshore oil installations and the first operational sonar using non-linear acoustics. Mr. Chramiec, who M.S. degrees in physics and ocean engineering, holds five patents and has published 20 papers covering various underwater acoustic devices.
Robert B. Delisle is an Engineering Fellow at Raytheon's NM& IS. He has helped design, develop, and evaluate surface ship sonar systems for more than two decades and has participated in numerous at-sea sonar evaluations for the U.S. Navy and other allied navies. He has been involved in the design, development, and testing of mine hunting and classification sonars at Raytheon. Mr. Delisle holds a M.S. degree in electrical engineering from Renssalaer Polytechnic Institute.
