Abstract :
Methods of radio frequency interference suppression in radio astronomy are considered. Estimations of signal-to-noise ratio for temporal and frequency methods of RFI rejection are made. Implementation of these methods in real-time digital signal processing could be an effective mean for supporting radio astronomy observations in worsening radio ecology environment. Radio telescope RATAN-600 experience shows the advantages of such a processing.
