In radio astronomy, the radio spectrum is used to detect weak emission from celestial sources. By spectral averaging, noise estimation is reduced and weak sources can be detected. However, more and more observations are polluted by man-made radio frequency interferences (RFI). The impact of these RFI on spectral measurement ranges from total saturation to tiny distortions of the data. To some extent, the final spectral estimation can be preserved by blanking infected channels in real time. With… CONTINUE READING
