Survey of Underwater Acoustics

Course #PC3400

Est.imated Completion Time: 3 months

POC: NPS Online Support

Overview

Introduction to the physics of the generation, propagation, and detection of sound in the ocean. Topics include the active and passive sonar equations; radiation of sound; acoustic wave equation and wave propagation; the ray approximation, normal mode propagation, the parabolic equation approximation; propagation uncertainty; reflection of plane waves from plane boundaries; speed of sound and absorption; transmission-loss and detection-threshold models; horizontal and vertical linear arrays. Discussions include literature reviews and assignments focus on modeling of sonar equation components and data processing.
