Underwater acoustic signals are powerful scientific tools for probing large regions of the ocean which would otherwise be inaccessible. Oceanographers and other scientists use acoustic energy as a mechanism to examine the structure of ocean regions for a variety of purposes. Predicting the behavior of sound in different types of ocean environments is an extraordinarily difficult problem which has been studied intensely for many decades. The parabolic approximation, introduced to the oceanographic community more than a decade ago has proven to be a powerful and effective ocean acoustics propagation model. Whereas these models were once exclusively run on mainframe computers, the advent of fast microcomputer chips, together with operating systems that can exploit the powerful features of these chips, now makes personal computers an attractive tool for performing many propagation prediction computations. This paper describes a full-featured version of one such widely used underwater acoustic propagation model which runs on PCs under the OS/2 operating system. |
