Abstract: Deconvolution of wide-field images is a well-known problem with many interesting algorithms. In this paper we describe the solution developed for deconvolving wide-field images from the Mauritius Radio Telescope (MRT). MRT is a non-coplanar, Fourier synthesis T array operating at 151.5 MHz. The non-coplanarity of the MRT produces dirty images that are convolved by a position dependent point spread function (PSF). This paper mainly focuses on the methods developed for estimating the PSF of the array from the dirty images and translating the PSF estimated at a given declination to the PSF at any another declination.
