摘　　要：阐述了利用卫星信标和高增益标准喇叭天线,测量手动VSAT站天线接收增益的方法。由测量的天线接收增益计算天线接收效率,从而实现对天线发射增益进行估算。最后,给出了工程测量实例,证明了该方法的可行性,并对增益测量误差进行了分析,其均方根误差±0.28dB。A method of measuring manual VSAT receiving antenna gain by using the satellite beacon and high gain standard horn antenna is described in this paper. The receiving antenna efficiency is calculated by measuring receiving antenna gain, and consequently to evaluate the transmitting antenna gain. Finally, we give the examples of engineering measurement to prove the feasibility of this method. We analyze the gain measurement error and the results show that rms error of gain measurement is less than or equal to ± 0.28 dB.
