Training Session: ATI Course: Underwater Acoustics, Modeling and Simulation

July 20, 2015 - July 23, 2015 Columbia, MD

The subject of underwater acoustic modeling deals with the translation of our physical understanding of sound in the sea into mathematical formulas solvable by computers. This course provides a comprehensive treatment of all types of underwater acoustic models including environmental, propagation, noise, reverberation and sonar performance models. Specific examples of each type of model are discussed to illustrate model formulations, assumptions and algorithm efficiency. Guidelines for selecting and using available propagation, noise and reverberation models are highlighted. Problem sessions allow students to exercise PC-based propagation and active sonar models.

Training Session: ATI Course: Sonar Systems Design

July 21, 2015 - July 23, 2015 Newport, RI

This 3-day course provides an overview of sonar systems design and highlights how sonar principles are employed in low frequency (LF), mid frequency (MF) and high frequency (HF) sonar applications. The course provides a solid understanding of the sonar equation and discusses in-depth propagation loss, target strength, reverberation, array gain, and detection of signals and their application to practical systems. Physical insight and typical results are provided to help understand each term of the sonar equation individually. The instructors then show how the sonar equation can be used to predict the performance of passive and active sonar systems. The course also reviews applications of passive and active sonar for ASW, including bistatics, for monitoring marine mammals and for high frequency detection, localization and imaging.    The course is valuable to engineers and scientists who are entering the field or as a review for employees who want a system level overview. A comprehensive set of notes and the textbook Principles of Underwater Sound will be provided to all attendees. Students will also receive analysis tools that they can use to quickly assess systems performance in the ocean environment.
