RFI monitoring

Even if the site’s location is excellent concerning the electromagnetic environment produced by man-made signals, a mobile laboratory for monitoring RFI (Radio Frequency Interference) is fully operational at the site. This is mainly used together with a fixed station to detect and identify the sources of interferences to the Radio Astronomy Service.

The RFI monitoring is continuously performed in the frequency bands of the first light receivers. Whereas C- (especially above 6400 MHz) and K-band (almost everywhere in the band) show very large bandwidth fully RFI-free, P- and L-bands look more noisy. Therefore appropriate observational strategies and mitigation techniques must be implemented to get rid of RFI.
