摘要
基于跟踪雷达角度自动跟踪系统特性,提出了战斗机中断雷达角度跟踪的机动轨迹控制策略。推导了跟踪雷达角度自动跟踪系统的系统传递函数,研究了跟踪误差产生机理。以二维平面内导弹攻击为例,分析了导弹与战斗机的二阶相对运动模型。在此基础上,基于闭环反馈控制思想,提出了战斗机通过机动实现角度拖引,中断雷达角度跟踪的控制方法,推导了战斗机的机动轨迹控制律,给出了其解析形式。通过数值仿真,分析了该方法的适用性,为战斗机飞行员制定决策提供了依据。
The maneuver trajectory control strategy that can interrupt the radar angle tracking loop was proposed based on the characteristics of auto angle tracking system. The transfer function of auto angle tracking system was developed,and the error production mechanism was studied. Taking the missile attacking on two-dimensional plane as example,the second order relative motion model of the missile and fighter was analyzed. And then,a fighter maneuver control method for interrupting the radar angle tracking loop through angle pull-off was put forward based on close-loop feedback control. An analytical form of maneuver trajectory control law was derived. The applicability of the method was analyzed through digital simulation.The results provide a reference for fighter pilots in decision making.
