Abstract

Due to the diffraction limitation, images acquired from the electromagnetic distribution detection are blurred by a parabolic reflector imaging system and super-resolution algorithm is thus needed to improve the resolution. By using an effective algorithm, the point spread function (PSF) can be obtained as a function of frequency, however, the frequency of electromagnetic source distributions are rarely known. Therefore, this paper presents a method of estimating the frequency of electromagnetic source distribution by establishing the corresponding relationship between estimated PSF via the blind deconvolution super-resolution algorithm and frequency. And then we can determine the PSF with the estimated frequency and restore the image via LR iterative algorithm. Experimental results show that the proposed method can effectively estimate the PSF of the wideband electromagnetic source distribution and improve the resolution of the blurred image.
