Mine Warfare Essentials

3-Day Course

Summary

The three-day 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 side scan sonar 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.

Instructor

Straud Armstrong - Earned B.S. in Marine Sciences, M.S. and Candidacy for Ph.D. in Geological Sciences through the University of South Carolina, developing algorithms for sonar-aided mapping of complex marine and aquatic environments and teaching undergraduate courses. For more than 25 years he has been exploring and mapping seafloor features through SCUBA and ROV-aided inspections, AUV, Hull-Mounted and Towed sonar detection and classification. He served as an Applications Engineer with Teledyne Benthos and Technical Sales Manager for Klein Marine Systems helping explorers throughout the globe to achieve their goals with emphasis on sonar mapping technologies and applications. He has been an active participant in manned, unmanned (remote), and autonomous Naval REA and MCM exercises and contact reporting in support of the US Navy, NATO, and others. His teaching style emphasizes comprehension and experiential learning to develop student/trainee skills and awareness beyond the scripted curriculum.
