      Article
      Open Access
      Airborne hyperspectral cameras provide the basic information to estimate the energy wasted skywards by outdoor lighting systems, as well as to locate and identify their sources. However, a complete characterization of the ...

    • 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
      Open Access
      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
      Open Access
      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 ...

    • 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 ...
