A Ray Tracing Program for Convergence Zones.
Abstract
This memorandum describes a ray tracing program which has been written for the Datatron 205 to permit the computation of corrected spreading loss for convergence zone rays in a layered ocean. This program, called Ray Tracing Program VI, differs from Program II in two major respects: first, it includes a computation of the diffraction loss correction factor, alpha/f, needed in the vicinity of each caustic to give a finite value of spreading loss; and second, it limits printouts to those ranges at which the ray passes through the receiver depth. Rays are delineated by their values of vertex velocity, V sub x, rather than vertical angles at the source, and four types of ray paths may be computed, with a variable number of range cycles between source and receiver.
