摘要
利用低轨道卫星ＪＡＳ－１ｂ测试分析了实际通信时的多普勒效应、接收电平，得到了该卫星的地面接收天线不能使用单一偏振面的天线而必须采用交叉八木天线。
Doppler effect and the receiving level in the communication with Low Earth Orbit (LEO) satellite are tested and analysed. As the results, 1) the cross yagi antennais should be used, 2) the best time step to adjust antenna is 20s.
