摘　　要：高机动条件下地面机动目标运动模型的研究对于实现坦克火控系统的精密跟踪与射击解命中具有重要的意义。文章针对未来战场上常见的规避运动,采用交互式多模型(IMM)及其改进的算法进行机动目标运动模型的研究;针对目标状态间断点处射击解命中误差过大的问题,基于目标在间断点处运动状态的变化提出了改进的算法,并分别进行了仿真实验;仿真结果证明,该算法对于提高战车火控系统对于高机动目标的射击命中率具有一定的价值和意义。Target shooting under the condition of high maneuver will be the normal phenomenon on the battlefield in the future. The study on motion model of targets under the condition of high maneuver is very important, especially for the targets tracking and hitting problems. The IMM algorithm and its improvement are applied into the study. Aiming at solving the problem of the interrupting point, an improved algorithm of IMM is used to reduce errors. The results showed by Matlab prove its great effect.
