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. Each student will receive a copy of Underwater Acoustic Modeling and Simulation by Paul C. Etter, in addition to a complete set of lecture notes.
