Abstract:

Contents Measurements of normal-mode amplitude functions in a nearly-stratified medium Range-dependent normal modes in underwater sound propagation Inverse wave propagation in an inhomogeneous waveguide A solution of the wave sound equation in shallow water for real speed profiles and solid bottom underwater sediment A wave theoretic method for estimating the effects of internal tides upon acoustic wave transmission Effect of ship motion on sonar detection performance Deterministic methods of sound-field computation Stochastic methods of sound-field computation.
