    • A novel RFI detection method for microwave radiometers using multilag correlators 

      Díez García, Raúl; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2021-02-10)
      Article
      Accés obert
      Radio frequency interference (RFI) is an increasing problem in microwave radiometry, particularly for Earth observation, because the antennas are pointing toward the Earth. RFI has been observed at the L-band in European ...

    • Impact of signal quantization on the performance of RFI mitigation algorithms 

      Díez García, Raúl; Camps Carmona, Adriano José (Multidisciplinary Digital Publishing Institute (MDPI), 2019-01-01)
      Article
      Accés obert
      Radio Frequency Interference (RFI) is currently a major problem in Communications and Earth Observation, but it is even more dramatic in Microwave Radiometry because of the low power levels of the received signals. Its ...

    • On the detection of RFI through the correlation anomaly at different time lags 

      Díez García, Raúl; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Text en actes de congrés
      Accés obert
      Microwave radiometers can be considerably affected by Radio Frequency Interference (RFI). These man-made interference conceal the underlying natural signal, preventing the retrieval of geophysical variables. Adopting ...

    • On the potential of empirical mode decomposition for RFI mitigation in microwave radiometry 

      Díez García, Raúl; Camps Carmona, Adriano José; Hyuk, Park (Institute of Electrical and Electronics Engineers (IEEE), 2022-07-04)
      Article
      Accés obert
      Radio-frequency interference (RFI) is an increasing problem particularly for Earth observation using microwave radiometry. RFI has been observed, for example, at L-band by the European Space Agency’s (ESA’s) soil moisture ...

    • Quantization and sampling effects on microwave radiometry RFI mitigation algorithms 

      Díez García, Raúl; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Radio Frequency Interference (RFI) is an increasing problem in Microwave Radiometry, particularly for Earth Observation. It has been observed at L-band in ESA's SMOS (Soil Moisture and Ocean Salinity) Earth Explorer mission, ...

    • RFI mitigation in microwave radiometry using the Karhunen–Loève transform 

      Díez García, Raúl; Camps Carmona, Adriano José; Hyuk, Park (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Article
      Accés obert
      This study presents a new signal-processing method to mitigate radio-frequency interference (RFI), based on the Karhunen–Loève transform (KLT). The main property of this method is that it is adaptive and RFI-agnostic, that ...

    • SMOS third mission reprocessing after 10 years in orbit 

      Oliva Balagué, Roger; Martín Neira, Manuel; Corbella Sanahuja, Ignasi; Closa Soteras, Josep; Zurita Campos, Alberto Manuel; Cabot, François; Khazaal, Ali; Richaume, Philippe; Kainulainen, Juha; Barbosa, José; Lopes, Gonçalo; Tenerelli, Joseph; Díez García, Raúl; González Gambau, Verónica; Crapolicchio, Raffaele (Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-01)
      Article
      Accés obert
      After more than 10 years in orbit, the SMOS team has started a new reprocessing campaign for the SMOS measurements, which includes the changes in calibration and image reconstruction that have been made to the Level 1 ...

    • TriHex: combining formation flying, general circular orbits and alias-free imaging, for high resolution L-band aperture synthesis 

      Martín Neira, Manuel; Scala, Francesca; Zurita Campos, Alberto M.; Suess, Martin; Piera, Miguel; Duesmann, Berthyl; Drusch, Matthias; Colombo, Camilla; De Wilde, Don; Closa Soteras, Josep; Gandini, Erio; Díez García, Raúl; Oliva Balagué, Roger; Corbella Sanahuja, Ignasi (Institute of Electrical and Electronics Engineers (IEEE), 2023-04-19)
      Article
      Accés obert
      The Soil Moisture and Ocean Salinity (SMOS) mission of the European Space Agency (ESA), together with NASA’s Soil Moisture Active Passive (SMAP) mission, is providing a wealth of information to the user community for a ...
