A microwave interferometer technique which may be used as a diagnostic tool for determining the electronic properties of a moving plasma is described and analyzed. The plasma and microwaves are confined in a wave guide and longitudinal observation is employed. The complex reflection coefficient determined from resultant standing-wave pattern provides the means for obtaining the complex dielectric constant, conductivity, electron concentration and collision frequency of electrons with molecules in the plasma. The plasma used for these experiments is the reaction products of a gas detonation.
