A method of radio frequency interference (RFI) suppression in radio spectroscopy is described based on the analysis of the probability distribution of an instantaneous spectrum. This method allows the separation of the Gaussian component due to the natural radio emission and the non-Gaussian RFI signal. Examples are presented of computer simulations and of radio source observations with RFI suppression applied. The application of the real time digital signal processing for RFI suppression is shown to be an effective means for maintaining the sensitivity of radiometric measurements in radio spectroscopy, remote sensing, radio astronomy, etc.
