弹着时间可控的机动目标多弹协同制导律*

针对机动目标的多导弹齐射攻击，运用最优控制和卡尔曼滤波理论探索机动目标下弹着时间可控制导律问题。设计了一种最优弹着时间可控的制导律，它由指定弹着时间和预计弹着时间的误差作为反馈信号与传统比例制导律结合推导得出，称之为弹着时间可控制导律（Impact-time-control Guidance Law，简称ITCG），同时利用卡尔曼滤波估计了目标加速度。通过对作战模型情况的仿真，可以看出这种新型的制导律应用于引导多发导弹以指定时间同时攻击目标时的有效性和可行性。

Impact-time-control Guidance Law for Multi-missile Cooperative Model with Mobility of the Target Considered

According to multi-missile salvo attack for maneuvering target,it uses ontrol and Kalman filtering theory to explore the issue of impact-time-control guidance law,which also considers he mobility of the target.An optimal guidance law is presented,this guidance law is a combination of the well-known PNG law and the feedback of the impact time error.This new guidance law can be called ITCG(Impact-Time-Control Guidance),also it estimats the target acceleration by using Kalman filter theory.Simulation of severa...
