This paper introduces the concept and significance of track association, summarizes the problems that can be solved by track association and the difficulties that track association are facing. The research of the algorithm of the sea and air target track association is helpful to realize the automation of track association and improve the efficiency and accuracy. The true value track is interpolated by Lagrange interpolation method, and the sufficient coincidence of the fusion track and true value track are obtained.The distances between the corresponding track points are calculated and then compared with a given threshold to determine the corresponding relationship, so as to realize the automation of track association. The track association algorithm is proposed based on this process, which realizes the automation of track association and improves the accuracy and efficiency of track association.
