Jan Arvid Högbom (born 3 October 1929) is a Swedish radio astronomer and astrophysicist.
[citation needed] Högbom is most well known for the development of the CLEAN algorithm for deconvolution of images created in radio astronomy, published in 1974.
[2][3] This allows the use of arrays of small antennae, generating incomplete sampling data, to effectively simulate a much larger aperture.
[1][4][5] These methods pioneered by Högbom are still extensively used and combined, e.g. in the imaging of the central supermassive black hole of the Messier 87 galaxy.
[6][7] Högbom was elected member of the Royal Swedish Academy of Sciences in 1981.
