STATISTICALLY STABLE ESTIMATES OF VARIANCE IN RADIO-ASTRONOMY OBSERVATIONS AS TOOLS FOR RADIO-FREQUENCY INTERFERENCE MITIGATION
A selection of statistically stable (robust) algorithms for data variance calculating has been made. Their properties have been analyzed via computer simulation. These algorithms would be useful if adopted in radio-astronomy observations in the presence of strong sporadic radio-frequency interference (RFI). Several observational results have been presented here to demonstrate the effectiveness of these algorithms in RFI mitigation.
