Abstract: Aiming to solve the multi\|sensor group target refined track initiation problem, a centralized multi\|sensor group target refined track initiation algorithm based on moving state is proposed. In this algorithm, the preparatory group division and association are done based on the circulatory threshold model and the group centers at first. Second, many subgroups are obtained from the associated groups based on different sensors. The false tracks based on the subgroups from the same sensor are eliminated with the non\|exclusive modified logic algorithm and the same\|state track group obtainment model. The false same\|state track subgroups of the sensors are also removed with the multi\|sensor same\|state group association model. Finally, the track refined association and combination are
implemented by using weighted algorithm. The analysis results of the simulation data show that as far as the true track initialized, the false track restraint and the roubustness to the clutter are concerned, the general performance of this algorithm is better than those of the distributed multi\|sensor modified logic algorithm and the centralized multi\|sensor multi\|formation track initiation algorithm based on clustering and Hough transform.
