火星-地球通信链路预算方法研究

Research on Mars-earth Communication Link Budget

给出火星探测器与地球之间通信链路的预算方法,研究火星大气损耗、太阳闪烁损耗、地球大气吸收损耗、降雨损耗及热体噪声的计算模型,最后给出火星-地球通信链路预算实例,为火星-地球通信链路设计提供参考。

This paper presents the budget method of the Mars-earth communication link as well as the calculation models of Mars atmosphere loss, solar scintillation loss, earth atmosphere absorption, rainfall loss and hot body noise. At last, an example of Mars-earth communication link budget is given. This paper has some reference to the design of Mars-earth communication link.
