    • One-point microwave radiometer calibration 

      Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Closa Soteras, Josep; Duffo Ubeda, Núria; Durán Martínez, Israel; González Gambau, Verónica; Martín Neira, Manuel (2020-03-01)
      Article
      Open Access
      A method for internally calibrating microwave total power radiometers by using only one level of noise injection is presented. It is based on having a previous accurate characterization of the receiver noise temperature, ...
    • 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 ...
