During the tracking process of anti-ship missile's zoom and dive trajectory, the fixed model set can not precisely match actual load index and have influence on performance, use self-adaptive grid method to track. Based on zoom and dive attack trajectory model, without knowing load index, use self-adaptive model set interact multi-model algorithm to carry out simulation calculation analysis. The results show that, the algorithm can precisely track load index change trend, use self-adaptive to adjust model load index in real time, converge the model set to real motive mode, its track precision is better than fixed model set interact multi model algorithm.%针对反舰导弹跃升俯冲机动过程进行跟踪时,固定模型集合难以精确匹配实际过载系数,影响跟踪性能的问题,应用自适应网格法进行跟踪.在跃升俯冲攻击弹道模型的基础上,当过载系数未知时,应用自适应模型集交互式多模型算法,并进行仿真计算分析.结果表明:该算法可准确跟踪过载系数的变化趋势,实时自适应调整各模型中的过载系数,使模型集合向实际运动模式收敛,跟踪精度优于固定模型集合的交互式多模型算法.
