Coherence Studies for Synthetic Aperture Sonar

Abstract

This project, examined coherence with respect to time, space and frequency. As part of our work on this project we developed coherence models which incorporated the environment, via scattering and propagation models and performed analysis of experimental SAS data from a variety of systems. This work also explored the usable coherence domain in terms of environmental effects for detection and classification techniques based on coherence. Novel detection and/or classification Ideas may result from this systematic look at coherence.
