摘要
目标运动状态模型的建立是机动目标跟踪的关键问题．本文首先通过对目标加速度的运动建模．建立了具有时滞的目标状态运动学模型．然后,应用H∞滤波算法进行了跟踪．大射电望远镜50 m模型实验结果表明馈源舱在恒定速率运动的条件下,本文算法显著提高了徕卡(Leica)的测量精度．
The kinematical state model of the target is a key problem in the maneuvering target tracking. Based on the acceleration equation, we proposed for the target a kinematical time-delay state model in low velocity. An H-infinity recursive filter is applied to track the target. In the application of the 50m-model of a large radio telescope, the experimental results show that the algorithm remarkably improves the tracking performance of the Leica obviously when the speed of the cabin is constant.
