  • A Novel Algorithm for Ship Detection in SAR Imagery Based on the Wavelet Transform 

    Tello Alonso, Mª Victoria; López Martínez, Carlos; Mallorquí Franquet, Jordi Joan (IEEE, 2005-04-30)
    Article
    Open Access
    Carrying out an effective control of fishing activities is essential to guarantee a sustainable exploitation of sea resources. Nevertheless, as the regulated areas are extended, they are difficult and time consuming to ...
  • Circular synthetic aperture radar (C-SAR) system for ground based applications 

    Broquetas Ibars, Antoni; Porrata-Dòria i Yagüe, Ramir de; Sagués Piella, Lluís; Fabregas Canovas, Francisco Javier; Jofre Roca, Lluís (IEE-INST ELEC ENG, 1997-05-01)
    Article
    Open Access
    The authors present an SAR system capable of obtaining radar images from measurements carried out with antennas that describe a circular trajectory centred outside the target region. The analytical formulation of the ...
  • High-speed focusing algorithm for circular synthetic aperture radar (C-SAR) 

    Bara Iniesta, Marc Antoni; Sagués Piella, Lluís; Paniagua Nicolás, Fernando; Broquetas Ibars, Antoni; Fabregas Canovas, Francisco Javier (IEE-INST ELEC ENG, 2000-04-30)
    Article
    Open Access
    A new algorithm is presented which is capable of generating very fast high-resolution images for circular synthetic aperture radar (C-SAR) systems. Its main characteristic is that it allows the processing of data from such ...
  • Linear and nonlinear terrain deformation maps from a reduced set of interferometric SAR images 

    Mora Sacristan, Óscar; Mallorquí Franquet, Jordi Joan; Broquetas Ibars, Antoni (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2003-10-31)
    Article
    Open Access
    In this paper, an advanced technique for the generation of deformation maps using synthetic aperture radar (SAR) data is presented. The algorithm estimates the linear and nonlinear components of the displacement, the error ...
  • On the extension of multidimensional speckle noise model from single-look to multilook SAR imagery 

    López Martínez, Carlos; Pottier, Eric (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-02-28)
    Article
    Open Access
    Speckle noise represents one of the major problems when synthetic aperture radar (SAR) data are considered. Despite the fact that speckle is caused by the scattering process itself, it must be considered as a noise source ...
