Scientific paper

Radio astronomy studies the emissions of celestial sources through the radio spectrum. However, the exponential expansion of the telecommunications makes these emissions more and more corrupted by man-made radio emissions (RFI). Therefore, RFI mitigation is becoming a necessity in radio astronomy. In this paper, several aspects of this issue are developed. In particular, the RFI context for the frequencies between 10MHz and 4GHz is presented, examples of RFI migration strategy are given and some practical implementations are described.
