@article{Leshem2000MULTICHANNELIM, title={MULTICHANNEL INTERFERENCE MITIGATION TECHNIQUES IN RADIO ASTRONOMY}, author={Amir Leshem and Alle Jan Veen and Albert-Jan Boonstra}, journal={Astrophysical Journal Supplement Series}, year={2000}, volume={131}, pages={355-373} }

Radio-astronomical observations are increasingly corrupted by radio frequency interference, and on-line detection and filtering algorithms are becoming essential. To facilitate the introduction of such techniques into radio astronomy, we formulate the astronomical problem in an array signal processing language and give an introduction to some elementary algorithms from that field. We consider two topics in detail: interference detection by rank estimation of short-term covariance matrices and…
