摘要
采用分别测量地面天线系统的增益G和接收系统噪声温度T的方法,对几个地球站的G/T值(它是地球站的重要技术指标)进行了测量。结果表明:对4.193GHz而言,6个地面站的G/T值分别为31.11dB/k,30.57dB/k,31.34dB/k,31.93dB/k,31.42dB/k和31.26dB/k,达到了国际通讯卫星组织颁布的F2类地球站的标准。
The values of GIT （the ratio of the ground antenna system gain to the receiving system noise temperature）, which is an important technical index for the earth stations, have been measured for several stations by using the method of separately measuring the G value and T value. The results show that the values of GIT for 4.193 GHz are 31.11, 30.57, 31.34, 31.93, 31.42 and 31.26dB/k respectively for the six earth stations, which are up to the standard of F2 class earth station, issued by INTELSAT.
