Abstract

A method is introduced for using a single underwater sensor and knowledge of a shallow water environment to track a moving, multi-frequency, acousticsource. The motion of the source creates a synthetic aperture that is adaptively matched against an acoustic propagation model in a manner similar tomatched held processing. However, in this case, many more unknowns must simultaneously be determined. Results are presented for tracking using experimental data subject to unknown source speed, heading, level, and initial position. A new parallel adaptive method manages these simultaneous unknowns. Perturbations in the sound speed based on empirical orthogonal functions are used to extend the approach to operating when there also is uncertainty in this parameter. The performance of the tracking process with hydrophone data for various signal-to-noise cases is considered. (C) 1999 Acoustical Society of America. [S0001-4966(99)01209-6].
