Abstract

Preliminary tracking system design and analysis is typically done using simulated data in which the target truth is known and many techniques have been developed for evaluating performance under these conditions. However, there is a notable lack of any consistent approach for evaluating tracker performance for real data in which there may be an unknown number of targets of opportunity whose trajectories are not known. In addition, the background clutter/false alarm environment may be unknown so that an important analysis task is to determine the most accurate background models. This paper proposes a set of criteria for evaluating the tracks that are formed using real data collected in the field in the presence of an unknown number of targets of opportunity. These criteria include duration, update history, and measures of kinematic and data association consistency. A scoring method is developed and the use of these criteria for system design is discussed.
