Abstract

The central problem in multitarget-multisensor tracking is the data association problem of partitioning the observations into tracks and false alarms so that an accurate estimate of the true tracks can be recovered. Many previous and current methodologies are based on single scan processing, which is real-time, but often leads to a large number of partial and incorrect assignments, and thus incorrect track identification. The fundamental difficulty with this approach is that there is simply not enough information in single scan processing to properly partition the observations into tracks and false alarms. In this work we formulate the problem of data association for track initiation and extension using multiscan windows in order to obtain superior track identification. A model problem is investigated to show the effect of window size, probability of detection, probability of false alarms, and measurement error on solution quality and timings.
