A method of fuzzy data association between the measurement and the p rediction of object is proposed in this paper, based on the combination of fuzzy clustering means algorithm and decision logic algorithm. The Euclidean distance measure is replaced with Mahalanobis distance measure in fuzzy clustering means algorithm, making the similarity between the measurement and the prediction mor e accurate, and the decision logic algorithm is used for determining the associa tion relation. Simulation results show that the proposed method is simple, and i ts tracking accuracy in heavily cluttered condition is high. The method can be u sed for tracking multi target on road with automotive radar.
