Some Simple Propagation Models for Linear and Parametric Sources in Shallow Water.

reportActive / Technical Report | Accession Number: ADA094060 | Open PDF

Abstract:

An existing theory is extended to model the average field of sound propagating from directive sources in a shallow water waveguide. The role of narrow beam sources in the excitation of modes is explored. Sample calculations are given. Author
