Rapid Alternative Calibration Procedure Of Reverberation Chamber Using Coupling Transfer Gain Function
2020 IEEE INTERNATIONAL SYMPOSIUM ON ANTENNAS AND PROPAGATION AND NORTH AMERICAN RADIO SCIENCE MEETING(2020)
摘要
This study proposes an alternative fast calibration procedure for the estimation of the well-stirred condition of the reverberation chamber (RC) using coupling transfer gain function. The novel coupling transfer current gain function of RC environment is developed using the measured two-port S-parameters. The proposed procedure involves the determination of the frequency corresponding to the well-stirred operation (f(wso)) of RC through the assessment of RC EM-field distribution using high order goodness of fit tests, and checking of the requirements of the independent samples for the particular stirred environment. The proposed procedure requires a portion of time (around 30 minutes) as compared to the conventional field uniformity long RC calibration procedure.
