Course Content (Syllabus)
Sound propagation in the ocean. Description of the sea-water column, the sea surface, the solid rock bottom, and the sedimentary layers. Ray theory of sound propagation, diffraction of rays, layered approximation of the sea-water column, and ray tracing. The natural underwater sound channel. Normal-mode theory of sound propagation, modal expansion in shallow and deep waters. Parabolic approximation of sound propagation in depth- and range-varying underwater environment. Underwater sound detection systems, the sonar equation, echo features, noise, and reverberation. Acoustical transducers, sound-emitting devices, and hydrophones. Scattering and absorption of sound by air bubbles in sea water.
