Abstract:

This program, written in FORTRAN V, uses normal code theory to predict acoustic propagation, in a medium whose velocity profile varies slowly with distance from the acoustic source, over an ocean bottom whose depth and acoustic impedance change slowly with range. It calculates and then produces CalComp plots for given modes at any frequency in the medium described above of the following a Amplitude as a function of depth and the ray equivalent of any mode at given distances from a source and b Propagation loss as a function of range.
