| 摘 要： | 从理论上分析了天馈系统驻波比检测精度低的原因,针对此原因提出了利用三点校准法提高天馈系统驻波比检测精度的方法。该方法基于矢量方式,较传统校准方法考虑的维度更多、信息更全面,大幅提高了驻波检测的精度,消除了驻波检测过程中可能出现的因天馈系统阻抗特性不同而引起的驻波比检测结果不同的不良表现,并使驻波检测的结果不随检测信号形式的变化而变化,提高了天馈系统驻波比检测的稳定性和可靠性和用户满意度,实验验证了该方法的正确性和有效性。

| Abstract: | A calibration method for standing wave accurate measurement of antenna feeding system is proposed in this paper.The reason why the detection precision is not high enough is analyzed and then a method which utilizes the three point calibration method for increasing the detection precision is proposed.This method is based on vector with more dimensions in consideration,thus more comprehensive information to improve the detection precision of standing wave ratio.A variety of adverse effects caused by the system which may appear in the testing process are removed,and the test result does not change with the form of detection signals.The stability and reliability of the test result is improved.The correctness and effectiveness are demonstrated by experiment. |
