摘　　要：在上合期间,日冕和太阳风严重影响深空通信链路。论述了非均匀太阳风对深空通信的影响,综述了基于深空探测器下行信号的太阳风观测,以及通过反演技术进行太阳风和日冕特性研究的国内外进展。以我国的深空探测为背景,提出一套基于探测器下行信号的太阳风观测方案,并可利用现有探测器进行预先观测研究。在我国深空探测任务开始后,在数据通信和测轨的同时,进行全过程的观测实验。Deep-space telecommunications will be severely affected by solar winds and the solar corona during a Superior Solar Conjunction. In this paper we discuss effects of inhomogeneous solar winds on signals in deep-space telecommunications. The effects include intensity scintillations, phase scintillations, and spectral-broadening phenomena. We then give a comprehensive review of observations of signal scintillations induced by solar winds and solar coronal events using downlink signals from deep-space probes. Our review is based on our investigation of dozens of papers related to the subject. We propose a scheme to observe signal scintillations using communication signals of existing space probes. The scheme aims to advance the Chinese deep-space exploration plan. The scheme can be applied in conjunction with data communications and orbital measurements of deep-space probes once the Chinese deep-space exploration starts.
