| 摘 要： | 月球辐射噪声是月球探测中影响测控通信性能的重要因素,将直接影响地面测控系统的数据接收和测距测速性能.本文在借鉴国外相关领域研究的基础上,首次探讨了月球噪声对测控通信的影响机理和测试方法,建立了理论模型并进行了仿真分析.在嫦娥二号工程中,利用国内目前最大口径的18m测控系统对月球辐射噪声进行了长时间的测量,通过对试验数据和理论计算结果的对比分析,得到了月球辐射噪声在S频段和X频段对18m测控系统的影响规律,为我国后续月球与深空探测的测控与通信链路性能的设计提供了更精确的参考依据.

| Abstract: | The lunar noise is the important factor of influence on the performance of TT&C in lunar exploration.It affects the data received and the measurement of ranging and velocity.Based on the foreign research,the theory on the lunar noise influencement and the method of measurement is decribed in the paper.The system model is established and simulated.In the project of CE-2,the lunar noise for a long time is measured,using the antenna of 18 m,which is the largest aperture in China.After compareing the result of ... |
