Abstract
The problem of radio frequency interference (RFI) in radio astronomy has become very critical during the last several years. The real sensitivity of radio telescopes is degraded by industrial noise. A method of combating RFI is proposed using time-frequency analysis and its implementation via digital signal processing in real time is discussed
