ATI's Sonar Principles & ASW Analysis course
This three-day 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 andsensor systems and discusses directions
for research in response to the quieting of submarine
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.
