Abstract :
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 dEr/dr and radial correlation lengths Lr, important parameters characterizing plasma turbulence. The reflectometer hardware is described and example measurements presented.
