Abstract:
The principal task of a sonar system is to generate possible tracks of an acoustic source. Matched-field tracking [Bucker, J. Acoust. Soc. Am. 96, 3809--3811 (1994)] is a signal processing algorithm for this purpose that has minimum operator input. In this presentation, the method is applied to active sonar systems by extending the definition of covariance matrix elements. A sample simulation will be shown where operator-independent tracks are obtained at different noise levels.
