针对大气层外目标的双弹协同拦截中制导律设计

论文以大气层外弹道导弹目标为研究对象，考虑拦截弹中段发动机推力固定耗尽关机方式，针对多拦截弹拦截目标问题，提出一种基于零控脱靶量的双弹协同拦截中制导律。在基于零控脱靶量的中制导律的基拙上，以两枚拦截弹的预期拦截点作为协调变量，在两枚拦截弹在零控脱靶量满足末段制导要求情况下，调整两弹的预期拦截点使其一致。分析满足协同拦截的两枚拦截弹的中段初始条件，设计了相应的应对策略。该制导律具有通信负担低，鲁棒性较强的特点。仿真算例表明，所设计的双弹协同中制导律可以有效协调两枚拦截弹实现协同拦截。

Mid-course Design of Collaborative Intercepting of Two Interceptors for Exo-atmospheric Interception

this paper we design a midcourse guidance of two interceptors intercepting Exo-atmospheric Ballistic Missile based on zero-effort-miss. The guidance law based on zero-effort-miss guidance midcourse guidance,taking the expecting intercepting point of two interceptors as coordination variable, adjust the expecting intercepting point of two interceptors as one point under the circumstance that the ZEM of two interceptors meet the requirement of terminal guidance. later Analysising the initial state of two interceptors that could intercept the target collaboratively,and designing according strategies. simulation shows that the guidance law can adjust two interceptors accomplishing intercepting collaboratively with low correspondence and good robustness.
