| 摘 要： | 光学终端在激光星间通信中扮演着重要的角色.研究了单个光学望远镜及光学望远镜阵用作激光星间通信中的光学终端时的系统性能,从电磁辐射入手,分析比较了单个光学望远镜及光学望远镜阵的增益及光学接收终端的方向图与相关参数的关系.仿真不仅论证了激光星间通信需要极精确的指向角度,而且得出结论:使用光学望远镜阵作为激光星间通信系统的光学终端具有更大的优势.

| Abstract: | The optical terminal plays an important role in laser inter-satellites communication.The performance of optical telescope and TA(telescope array)as optical terminal in laser inter-satellites communication is researched.The comparison of relationship of gain and pattern of optical antenna gain and TA with related parameters is also analyzed using electromagnetic wave theory.The simulations show that laser inter-satellites communication needs very accurate point angle.The analysis results also show that TA is better than optical antenna as optical termianl in laser inter-satellites communication system. |

| Keywords: | laser inter-satellites communication optical terminal optical antenna gain factor TA(telescope array) antenna pattern |
