Modelling OTHR tracks for association and fusion

The Jindalee high frequency OTH radar network sensors are capable of detecting and tracking a very large number of tracks within surveillance regions that can overlap. The large number of tracks can lead to ambiguity especially on the regions boundaries. One potential solution to this problem involves the development of algorithms capable of associating tracks received from various sensors. This paper looks at the process of identifying suitable track fusion algorithms and also highlights the problem of generating a vast amount of reliable tracks from an OTHR tracker system.
