Radio frequency interference (RFI) mitigation has become a significant issue for current and future radio telescopes. This paper presents a new scheme for removing radio frequency interference from astronomical data. It exploits a priori knowledge of the transmitters, namely, their cyclostationary statistical properties. Two real‐time cyclostationary detectors are proposed and compared. Results on both synthetic and real data demonstrate the efficiency of this concept.
