      Bachelor thesis
      Restricted access - author's decision
      Uno de los entornos en los que es más difícil la comunicación es el medio acuático, donde las señales electromagnéticas se ven severamente atenuadas, por este motivo se utilizan alternativas como señales acústicas. No ...
    • In-orbit validations of SMOS full polarimetric equations 

      Torres Torres, Francisco; Corbella Sanahuja, Ignasi; Wu, Lin; Duffo Ubeda, Núria; Delwart, Steven; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2013)

      This paper analyzes the consistency of SMOS fully polarimetric measurement mode by comparing measured data over the ocean with the expected results. These last are based on an accurate ocean model provided by LOCEAN and ...
    • Spatial biases analysis and mitigation methods in SMOS images 

      Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Wu, Lin; Duffo Ubeda, Núria; Durán Martínez, Israel; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Restricted access - publisher's policy
      SMOS brightness temperature images show some residual artifacts as a function of spatial directions. Due to having different antenna patterns in each element, even if knowing them perfectly, a minimum reconstruction error ...
