摘要：

A study is made of the influence of large-scale plasma turbulence on the results from a diagnostic method that is based on enhanced scattering, of microwaves near the upper hybrid resonance and is highly sensitive to small-scale fluctuations. The resolution in radial wavenumbers that is provided by an enhanced-scattering correlation analysis of small-scale fluctuations with allowance for multiple small-angle scatterings of the probing and scattered waves alone, their paths is determined. The frequency spectrum of a wave that is back-scattered by the small-scale fluctuations involved in large-scale turbulent motion and undergoes multiple small-angle scatterings is analyzed.
