Measurements and Analysis of Reverberation, Target Echo, and Clutter: FY09 Annual Report for ONR
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 (ARL/PSU) 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 ARL/PSU. 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.
