A History of RFI Protection of Radio Astronomy and the Latest Threats

摘要

Radio Astronomy was born in 1931, out of K.G. Jansky’s effort to identify the origin of interference to transatlantic short-wave communications. The science progressed rapidly after the end of World War II, particularly following the detection of the HI line by Ewen and Purcell, in 1950. Efforts to protect radio astronomy observatories from radio frequency interference (RFI) commenced shortly after these developments.
