Abstract:

Aiming at the problems of the existing track anti-bias association algorithms lack the consideration of the characteristics and principal of the marine target track and the poor practical application effect, according to the comparative analysis results of typical measured data, combined with the characteristics of slow change of marine target position and stable spatial topology association, and based on the triangle stable structure, the anti-bias association algorithm for marine target track is designed. Firstly, the topological triangle is constructed, and the threshold is determined by the triangle matching coefficient and the track map matching coefficient, and the correlation coefficient of the track pair is obtained. Secondly, the maximum correlation coefficient is retained and the track pair correlation coefficient matrix is constructed. Finally, the maximum correlation coefficient and threshold discrimination principle are used to output the associated track. The experimental results show that the proposed algorithm achieves the effective correlation of all tracks, which is obviously better than the comparison algorithms, and has strong stability and robustness. It can effectively solve the problem of track association of maritime targets in practice, and has strong practicability.
