针对反导传感器网络中弹道目标的协同跟踪问题，提出了一种基于信息增量的弹道目标协同跟踪方法。分析了多传感器对弹道目标的协同跟踪问题，并建立了自由段弹道目标分段匀加速模型。在此基础上，对自由段弹道目标跟踪过程中，利用跟踪滤波的协方差阵信息获得每个传感器对目标的信息增量，并以信息增量最大为准则选择传感器对弹道目标进行跟踪，从而实现对弹道目标的有效跟踪。仿真结果表明：所提的方法能够及时动态地选择性能最佳的传感器对弹道目标进行跟踪，提高弹道目标整体的跟踪性能，实现对弹道目标的协同跟踪。
針對反導傳感器網絡中彈道目標的協同跟蹤問題，提齣瞭一種基于信息增量的彈道目標協同跟蹤方法。分析瞭多傳感器對彈道目標的協同跟蹤問題，併建立瞭自由段彈道目標分段勻加速模型。在此基礎上，對自由段彈道目標跟蹤過程中，利用跟蹤濾波的協方差陣信息穫得每箇傳感器對目標的信息增量，併以信息增量最大為準則選擇傳感器對彈道目標進行跟蹤，從而實現對彈道目標的有效跟蹤。倣真結果錶明：所提的方法能夠及時動態地選擇性能最佳的傳感器對彈道目標進行跟蹤，提高彈道目標整體的跟蹤性能，實現對彈道目標的協同跟蹤。

Aiming at ballistic missile target tracking problem in anti-missile sensor networks,a ballistic missile target collaboration tracking method based on information gain is proposed. Problem of multi-sensor collaboration tracking on ballistic target is analyzed,and piecewise-constant acceleration model for ballistic coast flight is established;tracking covariance information is applied to obtain information gain of each sensor on target when tracking the coast flight ballistic target,and select the sensor to track ballistic target based on maximum information gain. Simulation results show that the proposed method can select the optimal sensor timely and dynamically to track ballistic target,which improves integral overall tracking property of ballistic target and realizes collaboration tracking on ballistic target.
