摘　　要：为了提高目标飞行器的突防能力,基于视线(LOS)指令制导原理设计了一种协同制导策略。在建立目标飞行器、防御弹以及攻击弹相对运动模型的基础上,证明了LOS制导的可行性,得到了防御弹和攻击弹的加速度关系,并给出了防御弹的LOS指令制导算法;然后,将目标飞行器和防御弹作为一个协同体,为目标飞行器突防进行逆比例制导设计。该协同制导策略不仅用于目标飞行器规避攻击弹拦截,且使得防御弹在不具有速度和加速度优势的条件下也能成功拦截攻击弹。仿真结果表明:所设计的协同制导策略使防御弹具有较高的制导精度,有效提高了目标飞行器的突防概率,为实际工程应用提供了参考。To improve the penetration ability of a target aircraft,a cooperative guidance strategy is proposed based on line-of-sight（LOS） kinematics.Firstly,a interception model is established in which the target aircraft launches a defender missile against an attacker missile.It is proved that the LOS guidance scheme is appropriate for the defender,and the lateral acceleration ratio of defender to attacker is also acceptable.Then,a reverse proportional navigation guidance law is proposed for the target aircraft.It utilizes cooperation between the aircraft and the defender.This guidance strategy can avoid the attacker colliding with the aircraft,as well as make the defender intercept the attacker successfully with no speed and acceleration advantages.The simulation results show that the proposed strategy improves the penetration probability of target aircraft effectively,and can offer a reference for engineering application.
