摘要
卫星将是现代战场获取情报的主要来源。通过与数据中继卫星构建星间链路转发信息的方式,卫星可以实时传递战场情况。根据卫星轨道递推、卫星通信和实施链路监视的可行性原理,提出了一种星间链路监视模型,该模型通过对卫星轨道递推的仿真以及星间链路监视的几何构型要求,能够对可监视的目标卫星之间的星间链路进行时间预报和角度预报,为干扰和控制星间链路提供数据支持。还进一步论述了两种不同方式的轨道递推方法之间的结果差异,并就轨道递推精度对监视时间和卫星高低角方位角的影响进行了讨论。
Satellites are the main source of information in modern battlefield. Thraugh links with TDRSS, satellites can transfer war information in real time. According to the principles of satellite orbit simulation, satellite communication and the feasibility of monitoring links between satellites, the paper presents a link monitoring model. On the basis of the simulation of satellite orbit and geometry model required by the condition of link monitoring, this model can forecast the timetable of links between satellites and satellites＇ angle parameters. Besides, it also shows the diversity of two different orbit simulation methods, and discusses the influence of the diversity on the timetable and angle parameters.
