MetadataShow full item record
A full‐wave, pulse‐propagation model for three‐dimensional wave propagation in a Pekeris waveguide based on linear systems theory is presented. The randomly rough ocean surface and bottom are accounted for via coherent (average) reflection coefficients. Attenuation due to absorption in all three fluid media is included. Transmit and receive planar arrays with beam steering can be simulated and, as a result, vertical arrays and a single, omnidirectional point source are automatically included. A built‐in signal generator can simulate arbitrary amplitude and angle‐modulated carriers. Outputs from this model include plots of the magnitude and phase of the ocean surface and bottom reflection coefficients, the complex acoustic field across the receive array. Because of its highly modular structure, the model can also be used to generate pulse‐propagation solutions using any time‐harmonic solution such as normal mode theory or the parabolic equation method. Preliminary computer simulation results are presented.
