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.
