An Underwater Propagation Model for Personal Computers

This paper reports on the development and implementation of an underwater propagation model on an IBM-PC/XT/AT and compatibles. This interactive model graphically displays various propagation-related quantities chosen by the user. Moreover, displays of intensity versus range and depth are depicted with gray-scale or color, instead of the conventional monochrome ray-path display. Hardcopy capability is also included. This inexpensive portable system finds application in the workplace both at the office and aboard ships which use XBT´s and the like to estimate propagation conditions.
