摘　　要：现代舰艇反导中,及时、准确、有效地跟踪强机动的反舰导弹是反导武器系统中的一项关键技术。基于反舰导弹末端"蛇行机动"的运动特征,设计目标"蛇行机动"为直线运动模型和转弯运动模型的组合,并引入到构建的具有变结构的自适应网格交互多模型(AGIMM)算法和固定结构的固定网格交互多模型(FGIMM)算法中,在给定的初始条件下,运用MATLAB进行Monte Carlo仿真实验,比较分析了AGIMM算法和FGIMM算法的跟踪性能。结果表明:针对目标"蛇行机动"的强机动情况,所构建的AGIMM算法比FGIMM算法的估计精度高、位置和速度估计波动小,稳定性好,适应性强,具有一定的工程应用价值。It is a key technology to track strong maneuverable anti-ship missile accurately and effectively in modem anti-missile weapon systems. On the basis of ＂Snake-wriggling Maneuver＂ of anti-ship missile, an Adaptive Grid Interacting Multi-Model （AGIMM） algorithm with variable structure was designed, and to compare this Fixed Grid Interacting Multi-Model （FGIMM） algorithm with fixed structure was designed too. At the given initial conditions, Monte Carlo simulation experiments were carried on based on MATLAB and the capability of the two algorithms were analyzed. The simulation results show comparing with FGIMM algorithm, the AGIMM algorithm has higher estimated accuracy, better stability, stronger conformability and smaller error of estimation in position and velocity and has a certain application value, dealing with a strong maneuvering target.
