摘　　要：针对跟踪高机动目标,对交互多模型(IMM)算法的模型集进行了改进研究。给出了一种引入当前CS-Jerk模型的IMM算法,对做蛇形机动的目标采用了常速模型、转弯模型和CS-Jerk模型进行交互,解决了在蛇形机动中加速度变化率的影响问题。通过与基于匀速-转弯模型及匀速-转弯-JERK模型的IMM算法进行比较及Monte-Carlo仿真表明,该方法在跟踪高速高机动目标中显示出优越性,并进一步验证了该方法的可行性和有效性,对研究目标高机动追踪时有一定意义。Aiming at tracking highly maneuvering target, the improvement of the model set for the interacting muhiple model （IMM） algorithm was investigated. A IMM algorithm, introducing CS -Jerk model, was proposed in this paper, as for the S maneuvering tar- get, it adopted the constant speed model, turn model and the CS - Jerk model to interact, the issue about the rate of acceleration change in S maneuvering was soveld, meanwhile, it was compared with the IMM algorithm of CV - CT and the IMM algorithm of CV - CT - Jerk.. It demonstrates that this method shows the superiority in tracking high - speed, high - motor target through the Monte - Carlo simulation, indeed, it further validates the feasibility and effectiveness of this method and has certain significance in researching high maneuvering target tracking.
