摘要
分析了太阳噪声对NASA深空站天线接收系统噪声温度的影响,并根据目前我国航天测控系统各种口径天线接收系统噪声温度的实测数据,给出了太阳噪声对系统噪声温度影响的测量方法、数学模型,从而为月球探测和深空探测通信链路估算中外部噪声温度的计算提供技术依据。
The effect of solar noise on receiving system of NASA DSN is analyzed.According to the measurement of various antennas in our country,the method and model of measurement are provided,which supply a basis for determining the external noise temperature in lunar and deep space exploration.
