为解决激光驾束制导导弹攻击运动目标存在滞后的问题,提出了一种无滞后驾束制导系统方案,基于导弹动力学模型和目标运动学模型,用卡尔曼滤波技术估计导弹运动状态和激光束转动规律,生成附加补偿指令,叠加到导弹的控制指令中。仿真结果表明,该制导系统可以很好的解决激光驾束制导导弹在跟踪运动目标时的滞后问题。

In order to solve the lag problem of the laser beam-riding missile attacking moving target, a laser beam-riding guidance system without lag is proposed. Based on the missile dynamics model and the target kinematics model, the movement of the missile and the rotation law of the laser beam are estimated using kalman filter technique, a additional compensation acceleration order is generate, which is added to the missile control orders. The simulation result show that the beam-riding system without lag can solve the problem of the lag when the missile attacks a moving target.
