Abstract :
A simple method based on the invariance property of the cross-ratio of the bilinear transformation is described in which complex reflection coefficient values obtained with a reflectometer are traced back to calculable air line impedance standards. First experimental results obtained for various coaxial systems and frequencies up to 18 GHz are presented
