Abstract A new procedure for restoration of the plasma inhomogeneities with improved resolution is suggested. The procedure deals with the double weighted Fourier transform (DWFT) of the observed wavefield in coordinates of both receivers ρ = (x, y) and sources ρ 0 = (x 0, y 0) [1]. Phase increments between the sources and receivers, being found from DWFT representation, can be used for extracting information on small perturbations of the dielectric constant ε~(ρ, z) in a way similar to traditional radio tomography. The resulting resolution of the method is close to the diffraction limit Δρ = λh/D in the horizontal direction and Δz = λ(h/D)2 in the vertical direction, where h is the height of inhomogeneities and D is the length of the ground-based receiving system.
