An iterative algorithm which deconvolves Eric Weisstein's World of Math a sampling function (the "dirty beam") from an observed brightness ("dirty map") of a radio source. This algorithm is of fundamental importance in radio astronomy, where it is used to create images of astronomical sources which are observed using arrays of radio telescopes ("synthesis imaging"). Application of the CLEAN algorithm to a synthesis imaging observation is sometimes described as "CLEANING the image."
