Abstract :
Summary form only given. Doppler reflectometry is a radar-type diagnostic for fusion plasmas which was developed to study the interplay between the sheared propagation velocity of the turbulence and the turbulence spectrum. The shear-flow decorrelation of transport carrying turbulent eddies is the main candidate as it is responsible for the occurrence of transport barriers in the plasma. The frequency shift spectra of the returning microwave signal was shown.
