　　针对移动通信基站天线测试系统场地反射波的干扰问题，在此提出了一种基于矢量网络分析仪时域门设置的反射波消除方法。首先分析了不同种类的基站天线和测试时天线所处的状态参数，然后通过分析其对时域门选择的影响，得出了时域门设置需要满足的条件，最后综合权衡时域门参数的设置，将时域门设置到最佳状态。实测数据表明，该方法能够有效地消除测试场地反射波的影响，保证被测天线的测量准确性，仿真验证了方法的正确性与有效性。

For the reflection wave interference in a mobile communication base station antenna test system,a reflection wave elimination method based on the time?domain gate setting of vector network analyzer is proposed in this paper. The differ?ent types of base station antennas and antenna state parameters under test are analyzed. The satisfied condition needed for time?domain threshold setting is obtained by analyzing the influence of antenna type and state parameter on time?domain threshold se?lection. By balancing the time?domain threshold parameter setting,the time?domain threshold is set to the best state. The mea?sured data indictes that the method can eliminate the interference of reflection wave in test site and ensures the accuracy of an?tenna testing. The effectiveness and correctness of the method were verified by simulation experiment.
