| 摘 要： | 介绍了卫星间激光通信系统的构成,分析与比较了星间非相干的IM/DD系统和相干光通信系统的性能.指出对于同步卫星间这种超长距离的光通信系统,高的接收灵敏度是至关重要的,因而相干光通信技术更有优势;但对于中低轨道卫星光通信系统,由于多普勒效应的影响,采用IM/DD技术更为恰当. |
| 关 键 词： | 激光通信 星间链路 相干光通信 多普勒频移 |

| Abstract: | The inter-satellite laser communication systems are discussed in this paper. The performances of the IM/DD systems and coherent light-wave system are studied, it is pointed out that the coherent light-wave systems for space optical communication links are better between the GEO satellites, since the high receiving sensitivity is very important in this case. For the optical links between MEO and LEO satellites, IM/DD systems are aptitude as account of the Doppler effect. |
| Keywords: | laser communication inter-satellite links coherent optical communication Doppler frequency shift |
