Technical and Training Professionals,
Now is the time to think about bringing an ATI course to your site! If
there are 8 or more people who are interested in a course, you save money if
we bring the course to you. If you have 15 or more students, you save over
50% compared to a public course.
This catalog includes upcoming open enrollment dates for many
courses. We can teach any of them at your location. Our website,
www.ATIcourses.com, lists over 50 additional courses that we offer.
For 24 years, the Applied Technology Institute (ATI) has earned the
TRUST of training departments nationwide. We have presented “on-site”
training at all major DoD facilities and NASA centers, and for a large number
of their contractors.

This course provides an excellent introduction to underwater sound and highlights how sonar principles are
employed in ASW analyses. The course provides a solid understanding of the sonar equation and discusses in-
depth propagation loss, target strength, reverberation, arrays, array gain, and detection of signals.
Physical insight and typical results are provided to help understand each term of the sonar equation. The
instructors then show how the sonar equation can be used to perform ASW analysis and predict the performance of
passive and active sonar systems. The course also reviews the rationale behind current weapons and sensor
systems and discusses directions for research in response to the quieting of submarine signatures.
The course is valuable to engineers and scientists who are entering the field or as a review for employees who
want a system level overview. The lectures provide the knowledge and perspective needed to understand recent
developments in underwater acoustics and in ASW. A comprehensive set of notes and the textbook Principles of
Underwater Sound will be provided to all attendees.
