      Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Durán Martínez, Israel; González Gambau, Verónica; Oliva Balagué, Roger; Closa, Josep; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2018-12-21)
      Article
      Open Access
      The microwave imaging radiometer with aperture synthesis (MIRAS) is formed by 69 total power radiometers, of which three are the noise-injection type. Their calibration is reviewed on the basis of the data gathered during ...
