Ellis, Dale D.
The long-term goal of this work is to better understand and model reverberation and clutter in shallow water environments, and to develop techniques for Rapid Environmental Assessment (REA) and environmentally adaptive sonar. The current project is a continuation of a joint collaboration (N000140310420) between Defence Research & Development Canada Atlantic (DRDC Atlantic) and the Applied Research Laboratory of Penn State University (ARL/PSU) to analyze and model reverberation, target echo, and clutter data in shallow water. It allows the 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) on Wideband Clutter Characterization. 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. A fast shallow water sonar model that includes target echo and clutter is being developed and validated. Experiments will be proposed for the 2007 clutter experiment with NURC, and the data analyzed.
