A novel method to improve the measurement accuracy of mutual inductance transmission line parameters

In this paper, a novel method which can improve the measurement accuracy of mutual inductance transmission line parameters based on adaptive single-ended sweep incentive is presented. This method can eliminate induced voltage and improving the measurement accuracy significantly by nonlinear frequency analysis and adaptive signal processing technology. In addition, traditional method based on series R-L transmission line model, shunt capacitive effect is ignored. Obviously, algorithm is not accurate particularly for medium and long transmission line. The algorithm used for the measurement of transmission line parameters is based on the solution of differential equation using π-model transmission line. This paper presents the theory of the technique, the design of hardware platform and the results of the simulation experiments to demonstrate its performance.
