Doppler reflectometry spectra simulations with velocity shear layer

Abstract

Doppler reflectometry is able to provide information on plasma poloidal rotation from the frequency shift of the backscattered spectrum at oblique plasma probing. It is usually assumed that the Doppler effect is due to the fluctuation rotation at cut-off vicinity. Full-wave modeling of the Doppler reflectometry signal is performed in a slab plasma geometry with a given shear velocity layer with inhomogeneous turbulence having realistic wavenumber spectrum and radial distribution. The first part of the presentation is devoted to the description of the code and to a short recall of the developed tools needed to simulate Doppler reflectometry. The advantages and limitations of the simulations will be also discussed.
