摘要
介绍了地球站系统测量中等效全向辐射功率的基本概念,阐述了利用场地法对地球站系统最大等效全向辐射功率测量的原理和方法,推导并给出了场地法测量地球站系统最大等效全向辐射功率的计算公式。给出了工程测量实例(L波段16 m地球站天线最大等效全向辐射功率值的测量),并对地球站等效全向辐射功率的测量误差进行了分析。实验结果表明,其均方根误差±0.30 dB。
The Equivalent Isotmpic Radiated Power is introduced based on earth station system measurement. The principle and method of using field for measuring earth station maximum EIRP is described, and the calculation formula of earth station system maximum EIRP is derived. Finally, some engineering measurement examples are given （Measurement of L band 16 m earth station antenna maximum EIRP value）, and earth station EIRP measurement error is analyzed. The experimental results show that the rms error of gain measurement is less than or equal to ± 0.30 dB.
