| 摘 要： | 介绍了用于机动目标跟踪的变结构多模(VSMM)估计中可能模型集(LMS)算法。阐明了该算法通过剔除不可能模型,保留一般模型,激活与重要模型相邻的模型实现模型集的自适应原理,并给出了其实现步骤。采用LMS算法对恒加速(CA)机动目标跟踪的仿真结果表明,LMS算法的滤波效果优于交互式多模型(IMM)算法,算法简单易行、计算量小,可用于跟踪运动规律较复杂的目标。

| Abstract: | A likely-mode-set(LMS) algorithm which belonged to variable structure multiple-model for tracking maneuvering target was introduced in this paper.The adaptive principle of the algorithm was presented,which included deleting all unlikely models,remaining ordinary models and activating all models that were adjacent to a principle model so as to anticipate the possible system transition.The realization process was given out.The simulation using LMS algorithm with constant acceleration showed that the filtering of LMS was much better than that of IMM.The LMS algorithm was simple with less computation,which would be applied to track complex moving target. |
