摘要
利用α-β跟踪滤波器的状态空间方程和离散传递函数之间的转换关系,将位置和速度的滤波及预报估计问题,转化为Z域内讨论根轨迹中零极点的分布问题,对目标平衡跟踪时滤波和估计参数变化规律给予了一种新的解释。
Discrete transfer functions for the αβ Kalman tracking filters are presented.Filters for the update,as well as the prediction,estimates are considered in Z domain,and root locus for the zeros and poles are presented.A new comprehension is given to the steady αβ tracking filters.
