基于跟踪雷达距离自动跟踪系统特性,提出了战斗机中断雷达距离跟踪的机动轨迹控制策略.推导了跟踪雷达距离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,提出了战斗机中断雷达距离跟踪的控制方法,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范围,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 range tracking loop wasproposed based on the system characteristic of auto range tracking system. The transfer function of auto rangetracking system was developed, and the error production mechanism was researched. Taking the missile attac-king on two-dimensional plane as example, the second order relative motion model was analyzed. And then,the fighter control method used to interrupt the radar range tracking loop was put forward based on close-loopfeedback control. The analytical form of maneuver trajectory control law was derived. The application rangewas analyzed through digital simulation. The results provide the fighter pilots reference when making decision.
