    • SAR interferometric coherence in wide band systems 

      Sagués Piella, Lluís; Bara Iniesta, Marc Antoni; Fabregas Canovas, Francisco Javier; Broquetas Ibars, Antoni (VSP BV, 2000-02-28)
      Article
      Accés obert
      This paper presents a study of the interferometric coherence aimed to the understanding of the main sources of phase error of an operative wide band system. This objective is accomplished by finding a theoretical expression ...

    • Sparsity-based radar imaging of building structures 

      Lagunas, Eva; Amin, Moeness; Ahmad, Fauzia; Nájar Martón, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, we address imaging of the interior structure of a building using a reduced number of measurements in through-the-wall imaging and urban sensing applications. Unlike majority of the feature detection methods ...

    • Spherical wave near-field imaging and radar cross-section measurement 

      Broquetas Ibars, Antoni; Palau, Josep; Jofre Roca, Lluís; Cardama Aznar, Ángel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-05-31)
      Article
      Accés obert
      The paper presents a new inverse synthetic aperture radar (ISAR) algorithm intended for radar cross-section (RCS) imaging and measurement from scattered fields. The method, based on a spherical-wave near-field illumination ...

    • Study of structural elements in heritage buildings with ground penetrating radar images 

      Santos Assunçao, Sonia; Pérez Gracia, María de la Vega (2018)
      Comunicació de congrés
      Accés obert
      Maintenance and repairing or ancient buildings requires efforts and a wide knowledge of the structures. However, in many cases, the constructive methods, the distribution of supporting elements and the materials are unknown. ...
