METHOD FOR PANORAMIC MEASUREMENT OF UHF BIPOLAR REFLECTION COEFFICIENT

摘要

FIELD: radio communications.;SUBSTANCE: method provides information concerning measured parameter in accordance to formula including two calibrating measurements of reflection coefficient module: |A₁| - idling with reflection coefficient Γ₁; |A₂| - short circuit means with reflection coefficient Γ₂=-Γ₁, and also in measurement of reflection coefficient module |A_x| - UHF bipolar with reflection coefficient Γ_x and calculation of measured vale |Γ_x|_u according to formula Reflection coefficient module value |A₃| is additionally measured (or set) in case of synchronous load, and result of measurement |Γ_x|_u is used to derive target value |Γ_x| from formula where and cosψ is determined from frequency dependence of value |Γ_x|² _u, set by expression ;EFFECT: higher precision.;1 dwg
