    • 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
      Accés obert
      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
      Accés obert
      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
      Accés obert
      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 ...
