Hydrographic & Side-Scan Systems Training
Hydrographic & Side-Scan Systems Training Course Description
This three day-Hydrographic & Side-Scan Systems Training 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.
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
