Abstract <p>The characteristics of poloidal correlation fluctuation reflectometry diagnostics for a small-sized tokamak were studied using numerical simulations. The simulations were conducted using the method of fast synthetic diagnostics based on the linear (Born) scattering theory and including full-wave calculations of electric fields of microwaves in unperturbed plasma. The signal of microwaves scattering by density fluctuations was calculated in accordance with the reciprocity theorem using the data from gyrokinetic calculations of the space-time distribution of these fluctuations in plasma of the FT-2 tokamak. The frequency spectra of the synthetic scattering signals were compared with the spectra of density fluctuations in the scattering region obtained from gyrokinetic calculations. From synthetic scattering signals, radial profiles of the poloidal phase velocity of fluctuations were calculated and compared with similar profiles calculated directly from the gyrokinetic distributions of density fluctuations, as well as with the profiles of the poloidal <b>E</b> × <b>B</b> drift velocity of plasma.</p>
