摘　　要：对近场测量系统中由于电缆摆动引起的相位测量误差进行了实验分析 ,利用定向耦合器对相位的误差信号进行了提取 ,并进行了相应的计算机处理 .结果表明 ,利用定向耦合器可以实现对该相位误差的修正 .由于结构简单 ,架设方便 。A measurement analysis is made of phase errors due to flexing of cables in a Near field measurement system. The phase errors were picked up by using a directional coupler and computer processing. The result shows that the phase errors can be corrected greatly with this method, which has a wildly used foreground in Near field measurement with simple structure and easy setup.
