Abstract:

The current project is a joint collaboration between Defence Research Development Canada - Atlantic DRDC Atlantic and the Applied Research Laboratory of The Pennsylvania State University ARLPSU to analyze and model reverberation, target echo, and clutter data in shallow water. It allows the Principal Investigator PI to spend approximately three months each year at ARLPSU. The collaboration leverages programs in Canada, US, and a joint research project with the NATO Undersea Research Centre NURC. The primary effort is analysis and interpretation of data, together with development and validation of improved modeling algorithms. One focus is the performance of directional sensors in towed arrays. The PI participated in the Clutter 07 and BASE 07 Mediterranean sea trials with NURC another trial took place in 2009. The data from these and other sea trials are being analyzed. A fast shallow-water sonar model that includes target echo and clutter is being developed it will have bistatic capability and range dependence. The models are being validated as part of the ONR Reverberation Modeling Workshops. Although not part of ONR funding, when opportunity presents itself, the improved models will be used in DRDC Technology Demonstrators for the Canadian Forces.
