基于可能模型集算法的反舰导弹跃升俯冲过程跟踪

Tracking of Anti-ship Missile's Zoom and Dive Based on LMS

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。应用可能多模型集合算法,实时自适应调整工作模型集合,选择主要模型,删除不太可能模型,使模型集合向实际运动模式收敛,从而改善算法跟踪性能。仿真结果表明,该算法可准确跟踪过载系数的变化趋势,跟踪精度优于固定模型集合的交互式多模型算法。

Owing to the mismatch between tracking model and the real overload factor, tracking performance of anti-ship missile's zoom and dive trajectory is decreased. Adaptive grid interacting multiple model algorithm is used to adjust the overload factors in tracking models. The simulation results show that model set can converge to the real motion and tracking performance is better than the interacting multiple model with fixed model set.
