摘　　要：针对巡航导弹类目标的运动特性,建立了蛇形机动攻击弹道模型,提出了一种改进的交互式"当前"统计多模型算法。该算法通过引入高斯隶属函数对"当前"统计模型的加速度方差极限值进行在线调整,使其可适应不同机动程度的目标;将不同机动频率的当前统计模型作为子模型融入交互式多模型,通过不同机动频率子模型的相互作用,进一步增强交互式模型的自适应跟踪能力。仿真结果表明,该算法跟踪过程平稳,跟踪精度高,收敛速度快,计算量适中,可用于末端防空武器拦截巡航导弹类目标。The model of snake maneuver attack trajectory was established in response to the motion characteristics of cruise missile target with an improved interactive“current”statistical multimodel algorithm proposed.The proposed algorithm adjusts the acceleration variance limit value of the current statistical model online by introducing the Gaussian membership function,which can be adapted to different degrees of mobile target.Current statistical models based on different maneuvering frequency as child models are integrated into the interactive multiple model.Adaptive tracking ability of the interactive model is further enhanced through the interaction among different maneuvering frequency sub models.The simulation results show that the proposed algorithm has the advantages of stable tracking process,high tracking accuracy,fast convergence speed and moderate amount of calculation,which can be used for the end air defense weapon to intercept cruise missile targets.
