卡尔曼滤波器在战术导弹导航系统中的应用

APPLICATIOH KALMAH FILTER TO THE NAVIGATION SYSTEM OF TACTICAL MISSILE

研究了一种战术导弹的导航滤波器。在中制导段以地面雷达作为测量单元，应用最优估计理论，设计了被称为导航滤波器的广义卡尔曼滤波器，以便于提供目标的运动状态信息。建立了导航滤波器的数学模型，并进行了公式推导和数字仿真分析。仿真结果表明，该方案能有效地估计大机动目标的运动状态信息。

in this paper, a navigation filter for midcourse guidance oftactical missiles is studied. A fixed-based radar is used as measurementequipment. A navigation filter, using estimation theory, is designed. Itgives movement state of target. The mathematic model of navigation filteris established. Finally, a quantitative digital simulations are provided toshow that the scheme can work effectively to estimate the medi urn--rangehigh maneuvering targets.
