摘　　要：文章针对交互多模型算法(IMM)运算量大、模型集设定偏离真实目标机动轨迹等情况,通过将变结构交互多模型算法(VSMM)的机动检测准则进行改进,提出了一种基于位置误差检测门限的VSMM算法。通过将两种算法的跟踪效果进行仿真对比,结果说明文章所提算法能够较为有效地改善对机动目标的跟踪情况,具有一定的理论价值。Aiming at the problem of computation and model set doesn＇t meet the real situation in interact multiple models algorithm（IMM）,a new method for the variable structure multiple model（VSMM） algorithm using new maneuver detecting threshold is proposed.A simulation about the two filtering algorithms is put forward by this thesis and the simulation result shows that the stability of maneuver detecting of the algorithm raised by this thesis can be rised up,and it has some significance for theory.
