  • Direct geocoding for generation of precise wide-area elevation models with ERS SAR data 

    Mora, O; Agustí, O; Bara, M; Broquetas Ibars, Antoni (ESA, 1999)
    Conference report
    Open Access
    An improved technique for generation of Digital Elevation Models (DEM), capable of dealing with full scene images (100x100 km) coming from an interferogram obtained with ERS satellite data is presented. Starting from an ...
  • 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 ...
  • Navigation systems requirements for airborne interferometric SAR platforms 

    Bara, M; Monné, J; Broquetas Ibars, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Conference report
    Open Access
    It is well known that by means of airborne interferometric SAR systems it is possible to generate high precision digital elevation models (DEM), although these platforms are seriously affected by motion instabilities. These ...
  • Precise geometry simulation of interferometric SAR signal for air- and spaceborne sensors 

    Bara, M; Broquetas Ibars, Antoni; Closa Domínguez, Josep M. (IEEE Piscataway, 2000)
    Conference report
    Open Access
    A complete interferometric synthetic aperture radar (SAR) simulator has been developed. It achieves precise results by using geodetic models to represent the Earth's shape, and considering SAR effects such as range migration, ...
  • Procesado interferométrico de datos SAR de sensores aerotransportados 

    Bara, M; Broquetas Ibars, Antoni (Universidade de Santiago de Compostela, Servizo de Publicaciións e Intercambio Científico, 1999)
    Conference report
    Open Access
    SAR Interferometry is a useful tool which allows the generation of high-precision Digital Elevation Models of the Earth surface. The paper describes an operational scheme of an interferometric processor, applicable to ...
  • Sensitivity equations and calibration requirements on airborne interferometry 

    Mallorquí Franquet, Jordi Joan; Bara, M; Broquetas Ibars, Antoni (IEEE Piscataway, 2000)
    Conference report
    Open Access
    The usage of an airborne interferometric SAR to mass map production is strongly dependent on the capability of performing the data processing in a near automatic mode. One of the main limitations is related to both the ...
