Abstract :
The paper is dedicated to the algorithm for determination of residual factors of one-port vector network analyzer. The algorithm is based on using quasi-optimal unscented Kalman filter and presumes processing of changes in the measured frequency response of short-circuited airline. The model of the system contains three fixed reflectors. The frequency parameters of each of them are given by a limited number of counts. Frequency response of reflectors is calculated using spline interpolation. Estimates of residual error-box´s parameters were analyzed. The estimates received were compared with the results of verification in the time domain. Applicability of developed verification method is discussed.
