摘　　要：提出了利用频谱仪和标准增益喇叭测量卫星信标EIRP的原理方法,推导出卫星信标EIRP测量的原理方程。简述了大气衰减计算的简单公式和近似计算方法。对卫星信标EIRP测量误差进行了分析,结果表明其均方根误差≤±0.614dB。最后给出了测量实例,从而验证了该方法的可行性。In this paper,measuring principle and method of satellite beacon EIRP are put forward using spectrum analyzer and standard gain horn.Principle equation of measuring satellite beacon EIRP is derived.A simple formula and approximate method of attenuation calculation by atmospheric gases are described simply.Errors of satellite beacon EIRP measurement are analyzed,results show that RMS error of EIRP measurement is loss than or equal to±0.614 dB.At last,measuring example is given,and the method feasibility is proved.
