Abstract
The paper addresses the problem of filtering the phase noise of probing signals, using additional spatial field processing. This field processing relies on the Double Weighted Fourier Transform (DWFT). We have shown it is possible to reconstruct images of plasma irregularities with high resolution, using DWFT spatial processing for circular field measurements under conditions of phase noise of probing signals.
