Localization Accuracy of Track-before-Detect Search Strategies for Distributed Sensor Networks

Localization Accuracy of Track-before-Detect Search Strategies for Distributed Sensor Networks

The localization accuracy of a track-before-detect search for a target moving across a distributed sensor field is examined in this paper. The localization accuracy of the search is defined in terms of the area of intersection of the spatial-temporal sensor coverage regions, as seen from the perspec...
