Improving the Water Column Representation

The representation of the undersea environment has often been ignored, or at best static, or precalculated in distributed simulation. This paper details the efforts of a multidisciplinary team who have implemented a dynamic ocean model and sensor response in the Joint Semi-Automated Forces (JSAF) architecture. A variant of the Princeton Ocean Model was run off the North Carolina coast to provide the dynamic environment. The Shallow Water Acoustic Toolset (PC-SWAT) that modeled the AQS-14 sonar solved the sonar equation. A CORBA interface to JSAF was developed to replace the pre-calculated look-up tables with real-time sensor information. This system was demonstrated in April 2000 at the Naval Research laboratory and will be used in the Naval War College's Fleet Battle Experiment-Hotel in August 2000.
