    "abstract": "Observations of enhanced Doppler frequency shift effect of the highly\nlocalized microwave backscattering in the upper hybrid resonance are reported.\nThe experiment is performed at FT-2 tokamak, where a steerable focusing antenna\nset, allowing off equatorial plane plasma extraordinary wave probing from high\nmagnetic field side, was installed. A separate line less than 1.5 MHz wide and\nshifted by up to 2 MHz is routinely observed in the backscattering spectrum\nunder condition of accessible upper hybrid resonance. The enhanced frequency\nshift is explained by the growth of poloidal wave number of the probing wave in\nthe resonance. The new scheme for local diagnostics of fluctuations poloidal\nrotation based on this effect is proposed.",
