High Speed Laser Information Transmission Technology of Deep Space Between Moon and Earth

  • 摘要: 深空月地激光高速信息传输技术利用光波进行深空信息传输,相比于传统微波波段的信息传输技术而言,在同样传输数据率情况下,具有通信终端体积小、重量轻、功耗低等优点,数据传输过程中接收灵敏度更高。此外,由于激光光束较窄,能量更为集中,可达到更远的传输距离。针对深空月地激光高速信息传输技术,介绍了深空月地激光信息传输技术发展的必要性和迫切性,阐述了国内外深空月地激光高速信息传输技术的研究发展现状;论述了深空月地激光技术上的挑战和技术可实现性,可为我国深空激光通信的发展及其工程化应用提供参考。

     

    Abstract: The application of light wave for deep space information transmission will have the advantages of smaller terminal volume,mass and low power consumption under the same data rate,and the receiving sensitivity is high during the transmission process. Because of the narrow beam width,it can make the energy centralized and reach a long transmission distance. Using light wave as the information carrier of deep space exploration will have the advantages that the microwave band does not have. The feasibility of technology is described, and the research status of the moon earth laser information transmission technology is summarized,providing a reference for the development and engineering application of deep space laser communication in China.
