Abstract: We study the spectral dependence associated with the magnitude of errors in the evaluation of the amplitude of the side lobes of the point spread function. It was shown that the method of the reference image by changing the image spectrum restored inverse filtering can improve the quality of reconstruction.

Key words: improvement of the quality of radio images, point spread function with side lobes, image restoration.
