摘　　要：多枚反舰导弹同时对目标实施饱和攻击时,不仅需要反舰导弹能够满足零脱靶量,还要求反舰导弹能从期望的入射角度对目标实施攻击,或者战斗部以特定的命中角度侵入舰艇目标,以期获得最好的打击效果。基于航向平面内的导弹与目标之间的二维相对运动模型,应用有限时间稳定性理论,提出了反舰导弹的末制导系统有限时间收敛的充分条件,并根据这个充分条件设计了一种带角度控制的有限时间收敛导引律。仿真结果证明,设计的导引律能够满足脱靶量的同时,实现攻击角度控制。The implementation of multi anti-ship missiles saturation attack a target at the same time,not only need the anti-ship missile can satisfy zero miss distance,also called anti-ship missile to attack the target from the expected angle,or the warhead invade the target with a specific hit point,which would bring the best attack effect. Base the two dimensional relative motion model between the missile and the target,the paper proposed a sufficient condition for the finite time convergence of the terminal guidance systems of the anti ship missile by the finite time stability theory. And according to this sufficient condition,a finite time convergence guidance law with impact angle control is designed.The simulation results show that the designed guidance law can meet the miss distance and control the attack angle at the same time.
