A REVIEW OF THE U. S. NAVY UNDERWATER SOUND LABORATORY'S ISO-LOSS CONTOUR PROGRAM.

Abstract

The current status of sound field prediction at the U. S. Navy Underwater Sound Laboratory is described. A raytracing program has been written which produces iso-loss and iso-anomaly contours for a cylindrically symmetric, layered medium, with the gradient held constant within each layer. A simplifying prediction tool applicable in this situation, the F-line, is described. Predicted sound field discontinuities produced by rays that vertex near break-points in the velocity-depth structure are discussed. (Author)
