摘要
太阳上合期间,太阳风严重影响深空通信链路,严重时可能导致通信链路中断。论述了信道与太阳之间的距离是决定太阳风对深空通信信道影响的主要因素,并分析了太阳风对信道影响的具体特征。最后,以中国的火星探测任务为背景,从理论上分析可行的抵抗太阳风影响的通信信道改善策略。
During Superior Solar Conjunction, solar wind exerts severe effects on deep space communication link, which may lead to serious disruption. Distance between a channel and the Sun is the main factor to determine how serious the impact is on deep space communication. In this article, specific features of the impact caused by solar wind are analyzed. At last, based on China＇s Mars exploration mission, several feasible communication strategies verified by theoretical analysis are proposed to resist the impact of solar wind.
