“…[1] Track association is the collection of groups of tracks, as produced by signal followers, into composite tracks representing the combined features of those multiple track segments. The assembled tracks are believed to share a common attribute, typically a common origin and propagation path from their origin to the receiver [2].…”

-Modern passive sonar systems employ a high degree of automation to produce a track-level sonar picture.Further refinement of the track-level information is normally performed by a human operator. Providing automated assistance would reduce the operator's workload and is a key enabler for semiand fully automated sonar systems. The nature of the signals emitted by targets and of the underwater environment typically results in each target being represented by multiple track segments. A tool is required which can numerically describe the relationship between pairs of track segments so that those that apparently share a common origin can be identified automatically.The sample correlation coefficient, is a statistical measure of relatedness. This paper describes the application of a test based on that measure to compare tracks produced by a probabilistic data association filter from a set of towed array sonar data.
