Adaptive Acoustic Signal Detection
Abstract
The focus of this research is to determine the impact of our knowledge of ocean variability, as characterized by the sound speed profile, on ocean surveillance detection performance for situations of interest to the U. S. Navy. Signal detection theory provides a framework for determining optimal phase coherent detection and source localization algorithms and determining their performance. This framework allows us to incorporate directly the physics of acoustic propagation through a space-time variable medium into the structure of optimal algorithms. Thus the signal processing algorithms designed from this viewpoint have a built-in robustness to the environmental variability. Using these optimal algorithms we can determine the maximum attainable detection performance.
