摘要 针对交互多模型(IMM)算法对目标加速度估计误差较大的不足,提出了一种改进的交互多模型算法,通过对交互多模型输出的加速度信息进行均值滤波提高对加速度估计的精度。计算机仿真表明,与交互多模型相比,该方法对匀速目标特别是机动目标具有更好的加速度估计能力,且便于工程实现。 Owing to the error of target acceleration estimation using interacting multiple model (IMM) algorithm is relatively large, an improved IMM algorithm is proposed in this paper. The precision of target acceleration estimation provided by IMM can be improved by mean filtering. The computer simulation shows that the acceleration estimation ability of the proposed method is better than that of IMM, especially in the case of maneuvering target, and also the method can be facilitated to engineering.
