Abstract
This report describes a demonstration system for combining track information from a number of radar sites. The site track information is used to form system tracks for the entire area surveyed by the radars. The system tracker is currently limited to accepting data from up to 10 radars and can track up to 20 targets. The target positions and velocities are displayed graphically using earth centred coordinates: latitude and longitude. Targets with and without identification information can be displayed using different colours. The site tracking program is a track-while-scan (TWS) system that uses a relatively simple algorithm to associate observations with tracks. This association algorithm can only associate a target with one track and each track can only have one target associated with it. The track updating is performed using an a-Beta algorithm. The system tracker uses the Dempster-Shafer method of data fusion to assign probabilities of association between site tracks and system tracks. Each system track is updated using information from site tracks with a sufficiently probable association. The track updating is performed chronologically using a Kalman filter.
