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, alphaf, 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.
