Abstract :
In this paper, some specific problems in multi-target tracking of sector scan TWS radar are analyzed. Based on dual azimuthal sectors, we have proposed an approach for previous plot-track correlation, which reduces the times of gate correlation greatly. Besides, a target-emerge-time prediction algorithm that fixed the formula of adaptive alpha-beta filtering & predicting is also established via analyzing the difference between two consecutive sampling intervals to the same target. The simulations are given in the end
