  • A comparison of phase unwrapping techniques in synthetic aperture radar interferometry 

    Ferrando Bataller, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Conference report
    Open Access
    A comparison of different phase unwrapping techniques based on the least mean square error is presented. A testing environment based on simulated interferograms has been created in order to assess the methods described in ...
  • A new spectral analysis algorithm for SAR data processing of ScanSAR data and medium resolution data without interpolation 

    Ferrando Bataller, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Conference report
    Open Access
    This paper describes a new approach for ScanSAR data image generation, which performs efficient data processing and multilook operation without the need of interpolation stages. This new technique is based on the spectral ...
  • Accuracy assessment of SAR interferometry using the ERS-1 

    Broquetas Ibars, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 1995)
    Conference report
    Open Access
    A SAR raw data simulator and a SAR processor are used as a tool for performance assessment of SAR interferometry algorithms like the multi-baseline and multifrequency. Traditional algorithms have also been tested with real ...
  • 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 ...
  • Generation of precise wide-area geocoded elevation models with ERS SAR data 

    Bara, M; Romero, Matilde E. de; Mora, O; Broquetas Ibars, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Conference report
    Open Access
    The authors present an improved technique for the generation of digital elevation models (DEM), capable of dealing with full scene images (100×100 km) coming from an interferogram obtained with ERS satellite data. Starting ...
  • Interferometric SAR signal analysis in the presence of squint 

    Bara, M; Scheiber, Rolf; Broquetas Ibars, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Conference report
    Open Access
    In the following paper an analysis of the SAR impulse response signal from the interferometric point of view is expounded, with the intention of studying its phase behaviour in the presence of high squint values. The work ...
  • 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 ...
