Parametric calibrated reflectometer with simple implementation is proposed. Based on its mathematical model the systems of measurement and calibration equations are formed and their explicit solutions are taken. These solutions are led to the calculation of the imaginary parts of the unknowns. Moreover conditions of true value choice are determined. The results of experimental investigations of parametric reflectometer implemented in microstrip are also presented.
