Integrated track splitting suite of target tracking filters

Abstract

This paper presents new algorithms for multi-scan, single target and multi target tracking in clutter. The algorithms from the Integrated Track Splitting (ITS) family of filters model each track as a set of components, where each component has a unique measurement history which consists of zero or one measurement received each scan. For each component, as well as for each track, the state estimate and the a-posteriori probability of component existence are computed recursively. Three algorithms are presented in this paper. The ITS filter is a single target tracking algorithm. The Joint ITS (JITS) filter is a multi target tracking algorithm which calculates the a-posteriori probabilities of a..
