dc.description.abstractBy using a linear systems theory approach, an ocean medium transfer function based on the WKB approximation can be developed. The phase computations for the transfer function are made by evaluating the WKB phase integral. Two applications of ray acoustics theory are investigated as accurate, efficient alternatives to direct numerical integration of the WKB phase integral. Both applications base phase computations on signal travel time. The difference is their treatment of the sound-speed versus depth data pairs. One forms a sound-speed profile by using the piecewise linear approximation method while the other uses an Akima cubic spline fit to the data. Each method can identify source-to-receiver eigenrays and provide ray trace plots.en_US
