摘要
中低轨天基红外星座是一种新型的能对自由段目标进行跟踪的导弹预警星座,基于深空背景的空域覆盖性能是表征其对自由段目标跟踪能力的重要指标。文中分析了星座基于深空背景的空域覆盖性能的特点和规律;在此基础之上提出一种对导弹预警任务针对性很强的降维研究方法,得到单星全空域覆盖环的概念;并将降维法应用于空域连续覆盖星座设计,提出了单轨道全空域连续覆盖带的概念;还对降维法在非连续覆盖星座设计当中的应用进行了初步探索。
Low Earth Orbit(LEO) and Medium Earth Orbit(MEO) space based infrared(SBIR) constellation is a new kind of ballistic missile early warning constellation and it can track a ballistic target in its coast phase.The airspace coverage with the background of deep space is an important index of the constellation's capability to track a ballistic target in coast phase.The characteristics and regularity of the constellation's performance on airspace coverage with the background of deep space are analyzed.Based on this,a dimension reduction method which is highly applicable to the mission of missile early warning is put forward,and the concept 'all-space coverage ring with a single satellite' is obtained.Furthermore,the dimension reduction method is applied to design of continuous airspace covering constellations,and the concept 'street of all-space continuous coverage' is presented.Preliminary exploration into application of the dimension reduction method in designing a constellation with discontinuous airspace coverage is discussed as well.
