TRACKER: a sensor fusion simulator for generalised tracking

This paper presents a multisensor, multitarget tracking simulator TRACKER that can be used to demonstrate and evaluate airborne early warning and control surveillance systems. TRACKER is a Level 1 fusion surveillance software package that generates a unified object state vector and its measure of uncertainty for each tracked object based on cluttered multitarget augmented (kinematic and discrete type) measurements from multiple dissimilar sensors. It integrates sensors and other sources of information without requiring synchronism and unifies tracking and identification. The resulting track and identity estimates are of a higher quality than those from algorithm in which tracking and identification are carried out separately. The software package is modular in structure and consists of a tracking and data fusion component written in MATLAB, and a graphical user interface written in Java. The package is equipped with a scenario generator and a set of post-mission analysis tools
