Abstract
Numerical pulse propagation studies using two classical ocean waveguide models
are performed. The first model is a pressure-release surface with a rigid bottom. The
second model is a pressure-release surface with a fluid bottom. The analysis of the
two models is based on normal mode theory assuming a constant speed of sound in the
ocean. The magnitude and phase of the complex acoustic pressure field as a function
of frequency is calculated across a planar array of hydrophones. The time-domain
output electrical pulse from the center element in the array is also computed. The
computer simulation results for the two models are compared and discussed.
