摘　　要：针对多级助推段弹道导弹存在多个加速度突变点、机动性强导致跟踪难度大的问题,提出一种基于量测转换的强跟踪输入估计(STMIE)弹道导弹跟踪算法。在对多级助推段弹道导弹动力学特性分析的基础上,推导出雷达站东北上(ENU)坐标系下弹道导弹的运动方程,并通过将修正的无偏量测转换(MUCM)与STMIE算法融合,使得在导弹跟踪中应用STMIE算法成为可能。以典型的多级助推段弹道导弹为跟踪目标进行仿真校验,结果表明,本文算法对多级助推段弹道导弹目标跟踪性能优越,且算法复杂度较低,效费比高。It is difficult to track a ballistic missile with multi-stage boosters in boost phase for its acceleration changes abruptly several times and it is highly maneuvering. Therefore, a tracking algorithm of a ballistic missile based on strong tracking modified input estimation （STMIE） and modified unbiased converted measurement （MUCM） is proposed. Based on the analysis of the dynamic characteristics of a ballistic missile which contains multi-stage boosters, the motion model of the ballistic missile in the the East-North-Up （ENU） coordinate system is derived. And it becomes possible for the STMIE algorithm applies to the ballistic missile tracking through the combination of the MUCM and STMIE algorithm. To verify the tracking performance, a typical ballistic missile target with muhi-stage boosters is used for the simulation, the results show that the algorithm has a good tracking performance as well as low computational complexity and high benefit-cost ratio.
