基于雷达导引头角度跟踪特性的战斗机机动控制方法

通过分析导弹导引头角度自动跟踪系统的跟踪特性,明确了跟踪误差产生机理及对跟踪系统的影响,提出了战斗机规避导弹攻击的机动控制目标。以二维平面内导弹攻击为例,建立了导弹与战斗机的相对追逃运动模型。基于动态逆理论,对中断导引头角度跟踪的机动控制方法进行分析,推导了战斗机的规避机动控制律。通过仿真验证了该方法的有效性。

An Evasive Maneuver Control Method Based on the Characteristics of Radar Angle Tracking System

Optimal evasion from guided missiles is crucial for the subsistence of fighters in air combat. Based on the radar seeker system characteristics of automatic angle tracking system, the tracking error production mechanism is researched, and a maneuver control objective of avoiding the missile attack is put forward. Taking the missile attacking on two-dimensional plane for example, the pursuit-evasion models of the missile and the fighter are built up. And then, the analytical form of evasive maneuver control law is derived based on nonlinear dynamic inversion. The simulation results show that the effectiveness of the above designed method is verified
