| 摘 要： | 介绍了用卫星源法测量卫星通信地球站天线的特点。简述了利用3dB和10dB波束宽度确定地球站天线增益的原理和方法。提出了利用外推法确定天线增益频段特性的一种简单方法。对波束宽度法测量增益的误差进行了分析和估算,其均方根误差±0.387dB。最后给出了某工程应用的C波段15m地球站天线增益测量结果,增益测量结果与理论计算结果吻合很好。

| Abstract: | Characteristics of satellite source method are introduced for measuring the antenna of satellite communication earth station.Principles and methods are described briefly for measuring earth station antenna gain by using 3dB and 10dB beam widths.A simple method for estimating gain frequency band characteristics by extrapolation is proposed.Errors of gain measurement are analyzed and estimated using beam width method,the results show that rms error of gain measurement is less than or equal to 0.387 dB.Finally,gain measurement results are given for C-band 15m earth station antenna,which shows good conformity to theoretical calculation. |
