The correlation Doppler reflectometer system consists of two 50-75 GHz reflectometers with a selectable O/X-mode polarization. Launching from the same tilted antenna allows the measurement of the radial electric field shear dE/sub r//dr and radial correlation lengths L/sub r/, important parameters characterizing plasma turbulence. The reflectometer hardware is described and example measurements presented.
