| 摘要: |
| 对武器系统来说，越早完成弹道导弹群目标分裂跟踪，准备时间就越充分；但另一方面如果群目标分裂过早，在跟踪过程中极易发生混批、错批等问题。本文提出了弹道导弹群目标跟踪分裂算法：首先分析群目标形成与跟踪策略，论述了IMM-UKF滤波框架，然后对群目标分裂算法进行了数学建模，分析了影响群目标分裂性能的各种因素，最后采用Pareto改进方法解决了多目标规划问题求解。仿真结果表明，该算法能够达到群目标尽早分裂与群内目标关联稳定度之间的平衡。 |

| Abstract: |
| For the weapon system, the earlier the group target splits, the more adequate the weapon system prepares. On the other hand, if the group target splits too early, it is easy to bring about mixed batch, wrong batch and other problems. This paper proposes a group target splitting algorithm for ballistic missile target tracking. Firstly,the group target formation and tracking strategy is analyzed and the IMM-UKF filtering framework is discussed. Then the mathematical model of the group target splitting algorithm is set up and the various factors that affect the group target splitting are analyzed. Finally, a Pareto method is proposed to solve the splitting problem. The simulation results show that the proposed algorithm can achieve the balance between the early splitting of group target and the association stability of intra-group targets. |
