ATI's Hydrographics & Side-Scan Systems course


Share |

Summary:

    Technical Training Short On Site Course Quote

      This three-course presents the key concepts needed to understand the state-of-the-art and practical use of bathymetric and side-scan sonars. It covers various classes of sonar systems, including multibeam, multitransducer, and interferometric. It provides the theory, system parameters, and design issues required to predict the system performance and accuracy of current and proposed equipment.

      The course emphasizes realistic expectations based on field operations. Case studies will provide a solid understanding of the major issues and effects. Noise testing and performance limitations of noise is covered as are the relationships between position, attitude, and bathymetry.

      The course presents some of the latest techniques used for topographic data review. The course is valuable for users of sonar records, for operators of equipment, and for scientists and engineers involved in the development and evaluation of sonar equipment. The course will discuss both commercial and military applications. All attendees will receive a complete set of notes and the text Side Scan Record Interpretation.

    Instructors:

      Jack Capell has over 30 years of experience in the design and application of multibeam sonar systems. He began his sonar career as the Manager of Electronics at the Harris ASW Division of General Instrument (now SeaBeam Instruments). He retired as a Senior Analyst in Advanced Development. His duties at SeaBeam included design, fabrication, and implementation of hardware and signal processing algorithms for sonars. He lead the test and evaluation efforts for many multibeam installations. He did noise studies for performance predictions of multibeam sonars on various vessels. He has given training courses on the operation and maintenance of multibeam systems. He is currently a consultant for companies in the sonar field.

      Garry Kozak attended Wayne State University, Detroit, majoring in Electrical Engineering. He has over 30 years of service to the oceanographic community, including 25 years in search and survey operations with side scan sonar. He is a world recognized expert in the interpretation of side scan sonar data. For the past 20 years he has been employed by Klein Associates, one of the leading manufacturers of side scan sonar systems. He has specialized in M.C.M. and C.O.O.P. application of side scan sonar and has over 19 years of hands-on experience in detecting mine-like objects.
