    • Atmospheric phase screen compensation in ground-based sar with a multiple-regression model over mountainous regions 

      Iglesias González, Rubén; Fabregas Canovas, Francisco Javier; Aguasca Solé, Alberto; Mallorquí Franquet, Jordi Joan; López Martínez, Carlos; Gili Ripoll, José Antonio; Corominas Dulcet, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2014-05-01)
      Article
      Accés restringit per política de l'editorial
      In this paper, a new model-based technique for the compensation of severe height-dependent atmospheric artifacts, using ground-based synthetic aperture radar (SAR) data over mountainous regions, is proposed. The method ...

    • DInSAR pixel selection based on sublook spectral correlation along time 

      Iglesias González, Rubén; Mallorquí Franquet, Jordi Joan; López Dekker, Francisco J. (Institute of Electrical and Electronics Engineers (IEEE), 2014-07-01)
      Article
      Accés restringit per política de l'editorial
      The reliability of any final differential synthetic aperture radar (SAR) interferometry (DInSAR) product is directly related to the phase quality of the interferograms involved in the processing. Performing an appropriate ...

    • Ground-based polarimetric SAR interferometry for the monitoring of terrain displacement phenomena-part I: theoretical description 

      Iglesias González, Rubén; Aguasca Solé, Alberto; Fabregas Canovas, Francisco Javier; Mallorquí Franquet, Jordi Joan; Monells Miralles, Daniel; López Martínez, Carlos; Pipia, Luca (2015-03-01)
      Article
      Accés obert
      Ground-based synthetic aperture radar (SAR) (GB-SAR) sensors represent an effective solution for the monitoring of ground displacement episodes. Initially, the most GB-SAR sensors were based on vector network analyzers ...

    • Ground-based polarimetric SAR interferometry for the monitoring of terrain displacement phenomena-part II: applications 

      Iglesias González, Rubén; Aguasca Solé, Alberto; Fabregas Canovas, Francisco Javier; Mallorquí Franquet, Jordi Joan; Monells Miralles, Daniel; López Martínez, Carlos; Pipia, Luca (2015-03-01)
      Article
      Accés obert
      Urban subsidence and landslides are among the greatest hazards for people and infrastructure safety and they require an especial attention to reduce their associated risks. In this framework, ground-based synthetic aperture ...

    • PSI deformation map retrieval by means of temporal sublook coherence on reduced sets of SAR images 

      Iglesias González, Rubén; Mallorquí Franquet, Jordi Joan; Monells Miralles, Daniel; López Martínez, Carlos; Fabregas Canovas, Francisco Javier; Aguasca Solé, Alberto; Gili Ripoll, José Antonio; Corominas Dulcet, Jordi (2015-01-01)
      Article
      Accés obert
      Prior to the application of any persistent scatterer interferometry (PSI) technique for the monitoring of terrain displacement phenomena, an adequate pixel selection must be carried out in order to prevent the inclusion ...
