摘要
随着人类对太空的探索日益加深,传统射频通信愈发不能满足高速深空通信的需求,各航天国家先后对深空激光通信技术开展研究.激光通信是实现空间通信的一种重要手段,相比于传统射频通信,激光通信具有通信速率高、终端载荷小、抗干扰能力强等优点,更适用于超远距离的深空通信.目前,美国进行的研究最多,且已成功实施了两次深空激光通信演示验证.本文针对已有的深空激光通信研究与演示结果进行综述,分析了实现深空激光通信的关键技术,对深空激光通信的发展历程与未来发展进行了探讨.
Abstract
With the deepening exploration of space by humans,traditional radio frequency(RF)communication increasingly fails to meet the demands of high-speed deep space communication.Various spacefaring nations have undertaken research on deep space optical communication technology.Optical communication is a crucial means of achieving space communication.Compared to traditional RF communication,optical communication offers advantages such as high communication speed,small terminal payload,strong anti-interference capabilities and so on,making it more suitable for ultra-long-distance deep space communication.Currently,the United States leads in research and has successfully conducted two deep space optical communication demonstrations.This paper provides a comprehensive review of existing research plans and demonstration results in deep space optical communication.It analyzes the key technologies for implementing deep space optical communication,reflects on the developmental history,and contemplates the future prospects of deep space optical communication.
