  • A comparison of different techniques for atmospheric artefact compensation in GBSAR differential acquisitions 

    Pipia, Luca; Fabregas Canovas, Francisco Javier; Aguasca Solé, Alberto; Mallorquí Franquet, Jordi Joan (IEEE, 2006)
    Conference report
    Open Access
    In this paper, a comparison of different techniques for compensating the atmospheric artifacts in Ground-Based SAR zero-baseline acquisitions at X-Band is presented. The way the fluctuation of atmospheric parameters like ...
  • Forest parameter estimation in the Pol-InSAR context employing the multiplicative–additive speckle noise model 

    López Martínez, Carlos; Fabregas Canovas, Francisco Javier; Pipia, Luca (2011-09)
    Article

    This paper addresses the problem of speckle noise on single baseline polarimetric SAR interferometry (Pol-InSAR) on the basis of the multiplicative–additive speckle noise model. Considering this speckle noise model, a novel ...
  • Polarimetric characterization and temporal stability analysis of urban target scattering 

    Margarit Martín, Gerard; Mallorquí Franquet, Jordi Joan; Pipia, Luca (IEEE Press. Institute of Electrical and Electronics Engineers, 2010-04)
    Article
    Open Access
    This paper studies the polarimetric-dispersion properties of urban targets and their evolution along time in terms of the geometrical configuration. The relations between target geometry and the scattering behavior have ...
  • Polarimetric coherence optimization for interferometric differential applications 

    Pipia, Luca; Fabregas Canovas, Francisco Javier; Aguasca Solé, Alberto; López Martínez, Carlos; Mallorquí Franquet, Jordi Joan (2009)
    Conference report
    Open Access
    In this paper, the potentials of polarimetric coherenceoptimization techniques for differential interferometric SAR (DInSAR) applications are examined. For this purpose, the cutting-edge approaches available in the ...
  • Polarimetric differential SAR Interferometry with ground-based sensors 

    Pipia, Luca (Universitat Politècnica de Catalunya, 2009-09-18)
    Doctoral thesis
  • Polarimetric temporal analysis of urban environments with a ground-based SAR 

    Pipia, Luca; Fabregas Canovas, Francisco Javier; Aguasca Solé, Alberto; López Martínez, Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2013-04)
    Article
    Restricted access - publisher's policy
    Revisiting time constitutes a key constraint for continuous monitoring activities based on space- and airborne synthetic aperture radar (SAR) acquisitions. Conversely, the employment of terrestrial platforms overcomes ...
  • PolSAR and PolInSAR model based information estimation 

    López Martínez, Carlos; Fabregas Canovas, Francisco Javier; Pipia, Luca (2009)
    Conference report
    Open Access
    Speckle for multidimensional SAR data may be modeled as the combination of multiplicative and additive noise sources. As demonstrated, the use of this noise model does not corrupt the estimation of physical information ...
  • Transpolarizing trihedral corner reflector characterization using a GB-SAR system 

    Ferrer, Pere J.; López Martínez, Carlos; Aguasca Solé, Alberto; Pipia, Luca; González Arbesú, José María; Fabregas Canovas, Francisco Javier; Romeu Robert, Jordi (2011-07)
    Article
    Restricted access - publisher's policy
    The use of a low-profile, lightweight, and easy-to-fabricate transpolarizing surface placed on one side of a trihedral corner reflector (TCR) as a polarimetric calibrator is presented in this letter. The transpolarizing ...
