Studies of fluctuating plasma rotation by means of correlation and Doppler microwave reflectometry in the Uragan- 3M torsatron were carried out. The application of two methods makes it possible to broaden the information about the rotation and structure of poloidal plasma oscillations. The correlation method has an advantage in l=3 torsatron, because this one is practically insensitive to the tilt angle of incident mm - ray to the reflecting surface. The pulsation of the poloidal velocity and the position of plasma layer in the region of magnetic islands were observed, that became stable upon the formation of the ITB.
