Introduction to Sonar

The sonar course aims to provide you with a good understanding of the theory and practice of sonar technology, and its applications in the defence industry, environmental surveying and related fields; placing emphasis on the practicalities of sonar systems rather than on rigorous mathematical analysis.

This course is ideal if you require a rapid introduction to 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
