Abstract

This paper provides some new results on track fusion for radars. In particular, it provides a relationship between the accuracies of fused tracks for co-located and non co-located radar sensors. The uncertainty volume corresponding to the fused estimate is smaller than the volume of the intersection of the uncertainty ellipsoids associated to the individual sensors. In terms of uncertainty volume, non co-located radars perform better than co-located radars. Analytical results for a study case are reported.
