S2K is an analysis tool programmed using Microsoft Visual C++ and residing in a Microsoft Windows NT environment. Both BEARTRAP and EER missions are Anti-Submarine Warfare (ASW) missions and are able to be analyzed on the same hardware system due to the use of the same recording media. This thesis develops a design framework for the S2K EER module, which is the software support needed to perform post mission processing for the EER mission. Two submodules of the design are also developed First is the Virtual Buoy Repositioning submodule, which uses acoustic data to correct errors in sonobuoy locations that are caused by aircraft navigational errors. Second is the Detection and Classification submodule, which processes the acoustic data to identify signal returns from the target. A preliminary analysis of incoming signals is performed using current techniques and exploring a new technique for signal classification.
