  • Real-time RFI detection and mitigation system for microwave radiometers 

    Forte Veliz, Giuseppe Francesco; Querol Borràs, Jorge; Camps Carmona, Adriano José; Vall-Llossera Ferran, Mercedes Magdalena (Institute of Electrical and Electronics Engineers (IEEE), 2013-10)
    Article
    Accés restringit per política de l'editorial
    Microwave radiometers are very sensitive passive sensors that measure the power of the thermal noise within a determined bandwidth. Therefore, any other signal present in the band modifies the value of the measured power, ...
