Development of Non-Traditional Detection Algorithms for Undersea Warfare
MetadataShow full item record
This study addresses the problem of hydrodynamically-based detection of the surface and subsurface wakes generated by transiting submersibles. Our primary objective is to investigate the wake intensity, its thermal signatures and detection potential. Research activities involved numerical, laboratory and field experiments. Our work was aimed at providing a comprehensive and systematic analysis of stratified wakes in a realistic oceanic environment and will offer valuable operational guidance in this regard. This project is most timely since numerical modelling capabilities, and understanding of environmental influences, have only recently reached the level at which all key physical components can be fully represented. The identification of detection vulnerabilities will affect the tactics of undersea warfare by narrowing search areas for USW. These techniques became particularly appealing in view of continuous technological advances in remote sensing methods, which have dramatically improved the accuracy of measurements in the submarine wake.
