Reduced Rank Wiener Filters in Optimized Coordinates for Partially Adaptive Filtering in Passive and Active Sonar Arrays
Abstract
We summarize the results of our most recent ONR Contract, "Reduced Rank Wiener Filters in Optimized Coordinates for Partially Adaptive Filtering in Passive and Active Sonar Arrays," ONR Contract N00014-01-1-1019, by giving a narrative account of what we have found for reduced-rank detection and estimation, conjugate direction Wiener filters, beamforming and diversity combining, and matched and adaptive subspace detection. We offer a discussion of open questions, as these inform our continuing work, under ONR support. The work reported here falls into the category of fundamental research addressed to passive sonar surveillance from large sonar arrays deployed in complex acoustic environments.
