Multi-way track association for over the horizon radar

In over-the-horizon radar, multiple ionospheric layers cause several tracks per target to be observed. This effect causes ambiguities in target identification and track coordinate registration. We propose a multi-way track association system for solving this problem by pre-selecting multi-way ("n-some") candidates through logical inclusion of the decisions of pairwise track association; and then classifying n-some candidates as associated and non-associated n-somes. The proposed approach is systematically described. The experimental results using simulated data are also presented.
