在文中讨论了大气层外三维拦截问题,得到了三维拦截问题的闭合制导律,在那里没有考虑目标的不确定机动及其它不确定(但非随机)的因素。实际上,即使目标不作机动,也总是存在着事先无法确定的因素影响着制导系统。如果在处理拦截问题时全然不考虑这些不确定因素的影响,那势必影响命中目标的任务,致使拦截目的难于达到。在讨论拦截 In this paper, the problem of three-dimensional interception outside the atmosphere is discussed and the closed guidance law of the three-dimensional interception problem is obtained. There are no uncertain maneuvers and other uncertain factors (but not random) of the target. In fact, there are always uncertain factors that affect the guidance system, even if the objectives are not motivated. If we completely ignore the impact of these uncertainties when dealing with interception issues, it will inevitably affect the mission of hitting the target and make it difficult to achieve the goal of interception.
