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.
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.
The course describes the essential mechanisms of underwater noise as it relates to ship/submarine silencing applications. The fundamental principles of noise sources, water-borne and structure-borne noise propagation, and noise control methodologies are explained. Illustrative examples will be presented. The course will be geared to those desiring a basic understanding of underwater noise and ship/submarine silencing with necessary mathematics presented as gently as possible. A full set of notes will be given to participants as well as a copy of the text, Mechanics of Underwater Noise, by Donald Ross.
Attendees will be immersed in the latest information from the exciting world of underwater autonomy. Through interactive workshops, informative panel discussions and product demonstrations, existing users of Kongsberg and Hydroid vehicles will have the opportunity to share their experience and knowledge to optimize their vehicle operations and non-users will learn first-hand about the capabilities and applications of AUV technology.
"The 2015 AUVX Users Forum will be an experience th at is not to be missed," said Duane Fotheringham, President of Hydroid. "Kongsberg and Hydroid take pride in the AUVs we build, and we want our customers to be able to learn about, and enjoy, their unparalleled capabilities in a hands-on way. Our AUVX forum is one of the best ways the global AUV and glider community can exchange ideas and increase their knowledge of these advanced systems."
The forum is open to all users of Kongsberg and Hydroid vehicles, with limited availability for non-users interested in learning more about the vehicles. The cost of attendance is $450 for all forum activities. The fee includes the welcome reception, presentations, panel discussions, workshops, demonstrations and the conference gala dinner, with entertainment. Additionally, attendees can enjoy a planned golf outing at the famous Renditions golf course, and an Annapolis Harbor sunset sail. Attendees traveling with guests will be offered a guest day excursion to Washington DC.
Teledyne Marine invites you to join us for a newly expanded users’ workshop in San Diego in which speakers, influencers, and attendees from around the globe will converge to explore, learn, and share their experiences on a broad range of technologies. Building upon Teledyne RDI’s long-standing ADCPs in Action and Teledyne Marine Acoustic Imaging’s Underwater Technology Workshops, this newly combined and expanded event will allow attendees to enjoy the one-on-one focus and industry camaraderie they’ve come to expect, with a new breadth of products, applications, and technologies to further enhance their user experience.
OCEANS '15 MTS/IEEE Washington DC will be held at the Gaylord National Resort and Convention Center on National Harbour, USA, from 19-22 October 2015.
The conference theme is Sea Change: Dive into Opportunity.
Topics with Special Local Interest
In addition to the Core Topics common to all OCEANS conferences, the Local Organizing Committee (LOC) has selected five topics with special local interest, as well as broad international significance. These topics were chosen by the LOC in keeping with the conference theme, Sea Change: Dive into Opportunity.
