基于三维空间的无人机规避攻击导引设计

摘要

According to the maneuvering of an Unmanned Aerial Vehicle ( UAV) when escaping from the attack of pure proportional guidance air-to-air missile,the pursuit-evasion mathematic models of the UAV and the missile were built up in three-dimensional space .The potential fields of the UAV and missile were analyzed by using artificial potential field theory .The situation model,pointing to the fastest increasing direction of UAV combat power potential,was established .A new combined escape guidance law was formed based on anti-proportional navigation guidance and anti-tail potential field power .Simulation was made for the cases of head-on attack scenario and stern attack scenario .The results indicate that the guidance law can complete escaping task effectively .%针对三维空间中无人机受到纯比例导引空空导弹攻击而采取机动规避的过程，建立无人机与空空导弹的相对追逃运动模型。基于人工势场基本理论，对空空导弹相对无人机的势力场进行分析，构建指向无人机的势力场增加最快方向的态势模型，利用反比例导引项结合反跟踪势场力项构成一种新的复合规避导引律，分别对迎头攻击和尾追攻击时无人机规避攻击进行仿真。仿真结果表明，该导引律能有效完成规避任务。
