  • Automatic vessel monitoring with single and multidimensional SAR images in the wavelet domain 

    Tello Alonso, Mª Victoria; López Martínez, Carlos; Mallorquí Franquet, Jordi Joan (ELSEVIER SCIENCE BV, 2006-12-31)
    Article
    Open Access
    Spaceborne Synthetic Aperture Radar (SAR) techniques constitute an extremely promising alternative compared to traditional surveillance methods thanks to the all-weather and day-and-night capabilities of Radar linked with ...
  • Brightness-temperature retrival methods in synthetic aperture radiometers 

    Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Camps Carmona, Adriano José; Duffo Ubeda, Núria; Vall-Llossera Ferran, Mercedes Magdalena (IEEE, 2009-01)
    Article
    Open Access
    Bightness-temperature retrieval techniques for synthetic aperture radiometers are reviewed. Three different approaches to combine measured visibility and antenna temperatures, along with instrument characterization ...
  • 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
    Open Access
    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)
    Conference report
    Restricted access - publisher's policy
    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
    Open Access
    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 ...
