中文摘要:
      针对预警机机动能力有限,在空战中易受到敌方先进导弹的“瞄准斩首”威胁的作战情况,研究由预警机或者护航机发射防御导弹以对抗来袭导弹,并在战场感知、信息共享、战术协同的条件下,预警机进行规避动作的主动防御方法设计。充分利用最优控制理论,在研究推导二维平面下目标飞机、防御导弹、目标导弹组成的三体攻防对抗问题中最优协同制导算法的基础上,通过三维空间主动防御过程的二维投影的方法,将三维主动防御制导律设计问题转化为两个相互约束的二维平面制导律(水平面和垂直面)设计问题,实现了协同制导律从二维向三维的扩展。仿真结果表明,相对于传统的拦截制导算法,所提出的制导算法不仅满足所需的拦截精度,而且具有较小的拦截过载,具有一定的优越性。
英文摘要:
      Aimed at the problems that an early warning aircraft is limited in maneuverability and is also subject to the “targeting dagger” threat of enemy advanced missiles in air combat, an active defense method is designed. First, an early warning aircraft or escort aircraft is to launch one or more defense missiles to combat incoming missiles. Second, the early warning aircraft is to evade them under condition of battlefield perception, information sharing and tactical coordination. Based on the research of the optimal cooperative guidance algorithm with the optimal control theory in the three body attack and defense confrontation problem composed of target aircraft, defensive missiles and target missiles under the two dimensional plane, the cooperative guidance law is extended from two dimensional to three dimensional through two dimensional projection method for active defense process in three dimensional space which transforms the design problem of the three dimensional active defense guidance law into two mutually constrained two dimensional plane guidance law (horizontal and vertical plane) design problems. The simulation results show that the proposed guidance algorithm can effectively intercept the incoming missiles under different attack modes in space and meet the needs of interception accuracy. The simulation results show that compared with the traditional interception guidance algorithm, the proposed guidance algorithm not only meets the required interception accuracy, but also has a smaller interception overload and has certain advantages.
