Modeling Pulse Transmission in the Monterey Bay Using Parabolic Equation Methods

Abstract

Acoustic tomography signal transmissions in the Monterey Bay is modelled using the time-domain parabolic equation method of Collins and Westwood (1991). Comparison of the model output with the measured arrival structures obtained in Monterey Bay in 1988 shows that this Fourier synthesis can produce good agreement with data. Furthermore, identification of the measured modal arrivals is possible by decomposing the PE model output into individual normal modes. Modal identification provides for the application of tomography in shallow water.
