中文摘要：

多重导弹的合作指导问题在这篇文章被考虑。在协作算法和本地指导法律一起被联合的地方，一个合作指导计划被建议。这个计划实际上建立层次合作指导体系结构，它可以提供一个一般答案给 multimissile 合作社指导问题。在要求导弹同时击中目标的保留攻击的情况中，集中、分布式的协作算法基于 impact-time-control 指导(ITCG ) 被导出法律。数字模拟被执行表明建议途径的有效性。

英文摘要：

Cooperative guidance problems of multiple missiles are considered in this article. A cooperative guidance scheme, where coordination algorithms and local guidance laws are combined together, is proposed. This scheme actually builds up a hierarchical cooperative guidance architecture, which may provide a general solution to the multimissile cooperative guidance problems. In the case of salvo attacks which require missiles to hit the target simultaneously, both centralized and distributed coordination algorithms are derived based on the impact-time-control guidance （ITCG） law. Numerical simulations are performed to demonstrate the effectiveness of the proposed approaches.
