多飞航导弹目标协同跟踪技术研究

Research on Synergistic Target Tracking of Multiple Cruise Missiles

摘要:

针对多飞航导弹对目标协同跟踪精度较低的问题,提出了一种基于弹载雷达组网和 GPS/INS组合导航的无偏不敏自适应融合跟踪算法。首先,通过领弹和攻击弹的优化布站,以有效提高多飞航导弹对目标的定位跟踪精度和突防能力；在时空协同的基础上,利用无偏不敏转换对各飞航导弹的目标量测进行预处理,以减小因旋转、平移和线性化误差所带来的影响；最后,结合统计双门限判决机制,利用自适应融合跟踪算法来有效实现多飞航导弹目标协同跟踪精度的提高。仿真结果表明,与现有的弹载雷达跟踪算法相比,该算法具有较高的定位跟踪精度。

Abstract:

To improve the synergistic tracking accuracy of multiple cruise missiles, an unbiased unscented adaptive fusiontracking algorithm based on missile-borne radar network was proposed. For this method, optimized arrangement of chiefmissiles and attack missiles was performed to improve the tracking accuracy and penetration capability of multiple cruisemissiles firstly. Then unbiased unscented transformation was used to reduce the effect of rotation, translation and lineariza.tion of each cruise missile measurement based on coordination of space and time. Finally, adaptive fusion tracking algo.rithm was performed to improve the tracking accuracy of multiple cruise missiles based on the double statistic thresholdmetric. Simulation results showed that target tracking could be finished more effectively than existing methods by using theproposed algorithm.
