Atmospheric Ray Tracing.

Abstract

A computer program has been written in FORTRAN to predict the acoustical ray paths in the atmosphere, as well as determining the transmission loss in air. The program accepts data in the form of a temperature or sound speed versus height profile. A wind velocity profile may also be entered. The program will produce a printplot of the ray trajectories, as well as a printplot of the transmission loss vs range. A CALCOMP plot of the ray trajectories may also be obtained. (Author)
