dc.description.abstractThe distribution of source- and receiver-noise in radio synthesis images is discussed, and it is shown that the source-noise is maximum at the position of the source but also appears in the off-source region because of the sidelobes. Analytical expressions are derived for the rms noise at any location of both 'total-power' and 'correlation' images. It is shown that under certain conditions, deconvolution can remove the source noise from the off-source region in snap-shot images. Some of the results are verified experimentally.en
