A simple method for making real-time measurements of complex reflection coefficient px is described. The technique uses a hybrid tee and two crystal detectors to provide analog outputs from which the reflection coefficient is obtained. Sample measurements of px made at 34.3 GHz are presented which indicate a precision of greater than 0.02 units and 0.05 radians in magnitude and argument, respectively, for 0.1 ≤|px|≤ 1.0.
