摘要
针对当前机动目标跟踪算法中跟踪模型与再入目标实际运动差别较大,影响跟踪精度的问题,根据弹道导弹再入段的特点,分析目标运动状态,推导出一种基于再入类弹道目标模型的目标跟踪算法,并与基于CA模型的目标跟踪算法做了性能比较,结果表明,该算法具有可行性,可以提高对目标的跟踪精度。
Focusing on the tracking precision problem caused by mismatch of tracking model with the real movement of modal reentry ballistic missile in current algorithms,a maneuvering target tracking algorithm based on ballistic model was presented by analyzing the ballistic characteristic of reentry missile and the missile dynamics.Then the algorithm was compared with target tracking algorithm based on CA.The simulation results show that the method is right and feasible.The performance of tracking target can be improved significantly with the algorithm.
