However, due to the difference of signal-to-noise ratios of separate radar sites, there usually exist some radar sites that have not initiated a target track, hence target localization accuracy can not be improved to the best. So an interesting problem is how to use target tracking information provided by other radar sites to improve the detection performance of the radar sites that have not initiated the target track. In this paper, a track initiation algorithm based on tracking information is proposed. Firstly, the target tracking information provided by the radar sites that have already tracked a target is transmitted to the radar sites that have not initiated the target track. Then, a predicted gate is established according to the tracking information and target dynamic model. Finally detection thresholds in the predicted gate are adjusted under a constant probability of false track initiation, and target detection and track initiation are accomplished. Numerical results indicate that the proposed algorithm can significantly improve the probability of target detection and target track initiation.Read More
