摘要
天馈线系统产生的无源互调干扰有其独特性,实践中多采用测试仪表现场排查方法,存在效率低下、准确率低等问题。针对这些问题,提出了利用基站系统作为互调检测硬件平台的天馈线干扰非现场排查法,可以通过干扰频谱数值对比,从复合干扰中分离出由天馈系统引发的互调干扰并对其进行定性,因而提高了检测排查的效率和准确性。
The passive intermodulation interference has unique characteristics. Traditional test meth- ods to this interference are in short of efficiency and accuracy. A new test method of intermodulation in- terference is proposed. By utilizing interference spectrum numerical comparison, the method isolates the intermodulation interference caused by antenna feeder from the composite interference. Therefore, the proposal improves the efficiency and accuracy of interference checking.
