Performance of centralized and distributed tyracking for multistatic ASW scenarios. NURC-FR-2006-001. June 2006.

Target tracking significantly improves the detection and localization performance of contact data; as such, it provides significant value added to the undersea surveillance processing chain. Centralized and distributed fusion architectures have complementary strengths: the former is best with high detection redundancy, high false alarm environments; the latter is best with low detection redundancy. Data fusion provides a robust surveillance picture that exceeds the performance of any given sensor in a field of like-performing sensors, and nearly matches the performance of the best-performing sensor when id performance dominates that of all other sensors. In all cases, simple track classification based on track duration, average speed, and heading stability provides additional performance gains.
