Abstract
Matched-field tracking algorithms, using as input a set of ambiguity surfaces generated by matched-field processing, have been successfully applied to track sources moving linearly or on a circular path at constant speed and heading. These algorithms assume that the track start and end surfaces are known a priori; this restriction is removed in the Piecewise Tracking Algorithm (PTA). In simulated data it is shown that using the weighted PTA the start and end surfaces of the statistically significant tracks, can be found with a mean absolute error of less than two, provided the track signal-to-noise ratio is greater than 13. A discussion of the PTA applied to data from the PACIFIC SHELF 93 trials is presented.
