摘　　要：针对飞机相比于攻击导弹在飞行速度和机动性上处于一定的劣势的情况，提出了一种飞机与拦截导弹协同对抗攻击导弹的制导策略。该制导策略基于线性二次型微分对策理论，可适用于对策3方（飞机、拦截导弹和攻击导弹）为任意阶控制的情形。由于与飞机之间的协同，拦截导弹可以实现弹道的及时调整，从而提高寻的性能。基于对策3方一阶控制系统动态假设进行了非线性仿真验证，结果表明该协同微分对策制导策略不仅可以实现对攻击导弹的有效规避或拦截，且相比于传统双方优化线性二次型微分对策制导策略，具有较好的寻的性能和较低的机动性能要求。In consideration of aircrafts＇ disadvantage in flight velocity and maneuverability compared with an attacking missile, the paper presents a cooperative differential game guidance strategy for securing them from an attack by launching a defending missile to intercept the attacker. This guidance strategy is derived based on the linear quadratic differential game theory and is suitable for the three participants （defender, interceptor and attacker） with any-order control. Because of the cooperation with the aircraft, the interceptor can adjust the flight trajectory timely to improve the homing performance. Based on one-order control assumption of the three participants, the nonlinear simulation was carried out and the experimental results show that this guidance strategy can realize the interception of the attacker. Compared with the two-sided optimization linear quadratic differential game guidance strategy, this strategy has the better homing performance and the lower maneuverability requirement.
