为了提高雷达位置伺服系统的跟踪能力,以目标信息滤波为基础,设计了雷达导引头伺服控制系统。运用经典控制理论,设计了导引头稳定控制回路;运用角度卡尔曼滤波及多普勒跟踪回路的修正信息,通过引入机动目标的当前统计模型,估计出天线转动的控制指令,实现了角度跟踪的前馈控制。经6DOF仿真环境验证,该方法不仅能够消除目标加速度的稳态误差,同时能够改善导引头的角跟踪精度。

In order to enhance the tracking capability of radar servo system, a radar servo controller was designed based on target information filtering. The stabilization loop was designed with correcting frequency of classical control theory, and by introducing "current" statistical model, with information collected from angle Kalman filter and Doppler tracking loop, the control command of rotational radar was estimated and feedforward control was achieved for angler control. Under 6DOF simulation, it's proved that not only target acceleration's steady-state error was eliminated, but also the angle tracking accuracy of radar seeker was improved.
