针对标准交互式多模型(Interacting Multiple Model,IMM)算法采用固定运动模型集导致运动目标跟踪精度下降的问题,本文提出一种基于滑动窗口的多模型自适应滤波(SWA-IMM)算法。通过计算运动目标与不同模型的匹配概率,利用滑动窗口判定法确定最佳匹配模型,改变模型集中最佳匹配模型的权重以达到模型集自适应的过程。结果表明,基于滑动窗口的多模型自适应滤波算法,在一定程度上提升了无人艇运动目标跟踪的准确性。
In order to solve the problem that the tracking accuracy of maneuvering objects decreases due to the use of fixed motion model sets in the standard interactive multiple model (IMM) algorithm, an interactive multi-model set adaptation based on sliding window filtering algorithm (SWA-IMM) is proposed in this paper. By calculating the model matching probability between the target and different models in the current model set, the best matching model is determined by sliding window decision method, and the weight of the best matching model in the model set is changed to achieve the adaptive process of the model set. The experimental results show that the SWA-IM algorithm proposed can improve the accuracy of maneuvering target tracking for USV to a certain extent.
