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.
