    "abstract": "Doppler reflectometry spatial and wavenumber resolution is analyzed within\nthe framework of the linear Born approximation in slab plasma model. Explicit\nexpression for its signal backscattering spectrum is obtained in terms of\nwavenumber and frequency spectra of turbulence which is assumed to be radially\nstatistically inhomogeneous. Scattering efficiency for both back and forward\nscattering (in radial direction) is introduced and shown to be inverse\nproportional to the square of radial wavenumber of the probing wave at the\nfluctuation location thus making the spatial resolution of diagnostics\nsensitive to density profile. It is shown that in case of forward scattering\nadditional localization can be provided by the antenna diagram. It is\ndemonstrated that in case of backscattering the spatial resolution can be\nbetter if the turbulence spectrum at high radial wavenumbers is suppressed. The\nimprovement of Doppler reflectometry data localization by probing beam focusing\nonto the cut-off is proposed and described. The possibility of Doppler\nreflectometry data interpretation based on the obtained expressions is shown.",
