| 摘 要： | 在卫星装备有环带波束天线的前提下,设计了由这类卫星构成的Walker星座内的星间链路,并对该星间链路的基本几何属性进行了仿真,证明了这类星间链路可以很好的解决卫星间天线对准的问题.首先,对环带波束天线、星间链路进行了简要的介绍,主要通过几何模型与几何参数方程的方式进行介绍和说明.其次,对于环带波束天线应用在星间链路中的可能性以及优越性进行了阐述,并且在特定的卫星星座当中,对这类星间链路中的卫星天线指向问题进行了仿真,从几何方面证明了该类环带波束天线使得卫星之间永久可视.再次,通过仿真结果中的链路俯仰角、链路距离等提出这一类天线的覆盖范围要求.最后,建立了具有环带波束天线卫星的Walker星座中的链路拓扑结构.

| Abstract: | Under the intuition of a satellite already equip the annular antenna, the Inter-Satellite-Links (ISL) in a Walker constellation made up of these satellites was designed. The basal geometric attributes of the ISL were simulated, which proved the effect of solving antenna collimation problem. First, a brief introduction of annular antenna and ISL were given, by the depiction of geometric model and geometric parameter equations. Then the possibility and advantages of equipping annular antenna into a satellite ... |
