Distributed versus Centralised Tracking in Networked Anti-Submarine Warfare

Abstract

This report describes a study of active sonar tracking, which explores the effect of networking sonars on tracking performance. We compare the tracking performance when sonars share detections (centralised tracking) with the performance when sonars share tracks (distributed tracking). Provided that the sonar layout and detection probabilities are such that multiple sonars have a reasonable probability (~30%) of obtaining detections from a target, we show that centralised tracking decreases the time to confirm a track on a target and improves the continuity of the target track. These improvements in target tracking occur at the expense of an increase in false track rate.
