Abstract:

LONG-TERM GOAL. Our long-term goal is to continue to assess the impact of temporal and spatial dynamics of oceanographic and meteorological factors on Navy sensors, systems, and operations. We will continue to improve our ability to exploit advances in remote sensing and climatology in the development of environmentally sensitive algorithms to improve ASW effectiveness in shallow-water, littoral regions. We intend to more closely integrate this technology with acoustic propagation and sonar performance prediction models whose ultimate application of these technologies is to provide sensor track optimization. Current work has focused on the Genetic Algorithm to solve the optimal search path problem. We have had sufficient success in two SHAREM exercises to warrant further development of the GA in the areas of target motion modeling, multiple constraint measures of effectiveness and user interface issues.
