Abstract

Radio Frequency Interferences (RFI) represents one of the major issues especially in single-dish low frequency radioastronomic observations. Several solutions have been investigated to face the problem. Among them a wide-band digital spectrometer is used together to a RFI monitoring station placed close to the radio-telescope and eventually supported by a RFI mobile laboratory. In this paper a system combining such as approaches is described. The first one is a wide-band FFT spectrometer designed for RFI purposes, then the second consists of a station dedicated to RF environment monitoring. Advantages and drawbacks of this hybrid approach will be shown.
