A data association algorithm for specific radio source using angle difference of arrival

A data association algorithm for specific radio source using multiple angle of arrival (AOA) is proposed. Conventional method has been inadequate for continuous data association because it associates nearest AOA with predicted angle by angle tracking and then loses track of true radio source. Proposed algorithm, featured by calculating weight for AOAs using angle difference of arrival and associating weighted centroid of AOAs with predicted angle, enables us to associate radio sources depending on relative range. Results of numerical experiments show efficiency of the proposed algorithm.
