发明名称 METHOD FOR DETERMINING ELECTRODYNAMIC CHARACTERISTIC OF HOMOGENEOUS TRANSMISSION LINE
摘要 FIELD: measurement technology including microwave measurements. SUBSTANCE: method involves excitation of transmission line loaded with microwave oscillations through high-frequency measuring channel in desired range, Measurement of extreme values of total reflectivity at input of transmission line and respective frequencies in desired frequency range, and determination of electrodynamic characteristics and input parameters of analyzed transmission line in each frequency band Δf = f<SB>max</SB>-f<SB>min</SB> and Δf = f<SB>min</SB>-f<SB>max</SB> using equations given in description of invention; according to method 1, wave impedance of high-frequency measuring channel and fixed values of two resistive loads are chosen in advance from given equations; according to method 2, wave impedance of high-frequency measuring channel and fixed value of one resistive load are chosen. EFFECT: improved measurement accuracy. 2 cl, 2 dwg, 3 tbl,
