摘　　要：通过建立导弹目标攻击简化数学模型 ,提出一种随机最优导引规律 ;运用卡尔曼滤波理论 ,引进了机动目标加速度和量测系统的不确定性。通过数字仿真 ,分别和传统比例导引规律、扩展比例导引规律相比较 。this paper,a new optimal guidance law is presented on the basis of the simplified Missile Target attacking model.The maneuvering targets acceleration and uncertainty of the measurement system have been considered in light of Kalman filter theory,and the optimum of this guidance law is shown through the comparative simulation conducted respectively on the same conditions for proportional navigations(PN) and augmented proportional navigation law(APN).
