单频干扰下BPSK接收性能恶化分析及应用

为了提高现有单频干扰下BPSK接收性能恶化分析方法的准确性和实用性,本文引入干扰信号相位作为随机变量,得出了新的分析方法。该方法首次准确量化了单频干扰下BPSK接收性能的恶化程度,普遍适用于BPSK调制体制下的卫星通信系统。给出了MATLAB数值仿真和现场实测结果。将其应用到探月工程嫦娥一号（CE-1）任务中,对CE-1通信系统受日本SELENE月球探测器信号干扰进行了准确的定量分析,为地面接收站的抗干扰设计以及中日双方探测器频率协调工作提供了依据。     

Scientific Progress in China's Lunar Exploration Program

Chang'E-1, the first lunar mission in China, was successfully launched on October 24,2007, which opened the prelude of China's Lunar Exploration Program. Later on, the Chang'E-2 and Chang'E-3 satellites were successfully launched in 2010 and 2013, respectively. In order to achieve the science objectives, various payloads boarded the spacecraft. The scientific data from these instruments were received by Beijing and Kunming ground stations simultaneously. Up to now, about 5.628 Terabytes of raw data were received totally. A series of research results has been achieved. This paper presents a brief introduction to the main scientific results and latest progress from Chang'E-3 mission.
