摘要
研究了多阶段协同拦截问题中多个飞行器分阶段发射协同拦截一个高机动目标.首先,给出了多阶段协同拦截问题的描述.由于测量噪声以及目标的不确定性,用一个动态分布描述目标的位置状态,该分布通过卡尔曼滤波得到.然后,基于最大拦截概率,将制导问题转化为覆盖控制问题以获得拦截器的期望位置.最后,基于传统的优化方法,给出了每个飞行器的制导控制律.
This manuscript investigates a multi-stage cooperative interception prob- lem in which a group of flight vehicles are launched successively to cooperatively in- tercept a high maneuvering target. First, the multi-stage cooperative interception problem is formulated. Due to the measurement noise and uncertainties, a dynamic distribution is used to describe the location of the target which can be obtained by Kalman filter. A coverage-based algorithm is proposed to obtain the expected loca- tions of the flight vehicles by maximizing the interception probability. Moreover, the guidance control law of each flight vehicle is given based on the classical optimization approach.
