摘要
阐述了激光通信相对于微波通信的优势在于其在卫星通信中的实用意义。分析了星地激光通信的发展现状,提出大气湍流限制星地激光通信系统的通信性能和激光链路的可靠性。针对星地激光通信的通信性能和瞄准捕获跟踪技术,综述了大气湍流对它们影响的研究现状。
In this paper we firstly have specified meaning of laser communications in the satellite the main advantages of optical communications and the communications, and then briefly introduced the development of satellite-ground laser communications that includes the realized experiments. At last, we have summarized the effect of atmospheric turbulence on the communications performance and the technology of pointing, acquiring and tracking of the satellite-ground laser communications.
