Summary:Performance evaluation of simultaneous tracking and identification (STID) systems consists of measures of performance, measures of effectiveness, and measures of force effectiveness. To investigate the capability of STID, we extend track purity to a current assignment ratio. Track purity determines the correctly associated measurements for a given scan where as the Current Assignment Ratio (CAR) determines the correct measurements for a given track. Using the CAR aids sensor management algorithms in determining which targets have robust features for target identification in clutter, such that the target can be tracked. The CAR enables effectiveness evaluation of STID systems for mission success. In the paper, we review the fusion performance evaluation literature, outline STID metrics, and demonstrate the use of the CAR in a scenario.
