    • A novel digital IQ demodulation for interferometric radiometers 

      Corbella Sanahuja, Ignasi; Martín Neira, Manuel; Vilaseca, Roger; Catalán Artigas, Albert; Torres Torres, Francisco; Suess, Martin (Multidisciplinary Digital Publishing Institute (MDPI), 2021-03-02)
      Article
      Open Access
      In the frame of an SMOS follow-on operational mission, a new instrument design is being developed based on the lessons learned from MIRAS, the SMOS payload. To reduce hardware complexity and mass, digital In-phase Quadrature ...
    • A pre-correlation RFI mitigation algorithm for L-band interferometric radiometers 

      Querol Borràs, Jorge; Camps Carmona, Adriano José; Pérez Portero, Adrián; Oliva, Roger; Onrubia Ibáñez, Raul; Ramirez Martinez, Juan Ignacio; Zurita Campos, Alberto M.; Suess, Martin; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      Radio Frequency Interference (RFI) is a major concern for both real and synthetic aperture radiometers. After the lessons learnt from SMOS, ESA is preparing the next generation of L-band interferometric radiometers with ...
    • RFI detection and mitigation for advanced correlators in interferometric radiometers 

      Pérez Portero, Adrián; Querol Borràs, Jorge; Camps Carmona, Adriano José; Martín Neira, Manuel; Suess, Martin; Ramirez, Juan Ignacio; Zurita Campos, Alberto M.; Closa Soteras, Josep; Oliva, Roger; Onrubia Ibáñez, Raul (Multidisciplinary Digital Publishing Institute (MDPI), 2022-09-01)
      Article
      Open Access
      This work presents the first RFI detection and mitigation algorithm for the interferometric radiometers that will be implemented in its correlator unit. The algorithm operates in the time and frequency domains, applying ...
