Wiki is a bit weak on iterative deconvolution algorithms.
The sort of thing you are asking about, or rather a version that
actually works in practice was invented in 1974 by Hogbom as the CLEAN
algorithm for radio astronomy. His original paper is online at:
http://www.astro.rug.nl/~vdhulst/SignalProcessing/Project1_data/clean_hogbom.pdf
Variants of this algorithm are still used today in aperture synthesis
although I prefer other deconvolution algorithms myself.
