Abstract

In order to replace the complicated operation of the traditional vector network analyzer, the portable magnetic resonance probe performance detection system has become a research hotspot. However, its measurement accuracy has not been high. This research aims to improve the traditional calibration algorithm. While eliminating the directional error, source matching error and reverse tracking error in the traditional single-port network model. The deviation of measurement results caused by the lack of standard calibration parts is eliminated. Compared with the existing algorithms, the accuracy of experimental results are significantly improved.
