Fundamentals of Sonar

This course is designed as a follow on to the Introduction to Sonar course.

The sonar course aims to provide an in-depth understanding of underwater acoustic principles, sonar technology and applications; underpinned by the physical principles and analysis. The sonar course is suitable for those requiring a rapid introduction to advanced sonar technology, its specification and applications; particularly:

  • Hardware and software design engineers new to sonar system design
  • Naval personnel involved in sonar commissioning or its application
  • Procurement/purchasing managers requiring to prepare tenders or specifications
  • Design managers
  • Project managers
  • Installation and maintenance engineers
  • Sales engineers.
