      This paper proposes an analytical formulation of the instrumental errors in multilevel hierarchic SAR architecture equipped with active phased array antennas. The basis of the study is the derivation of the so called ...
    • 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, ...
    • Signal-to-noise ratio equalization for TOPSAR mode using a nonuniform steering rate 

      Ruiz Rodon, Josep; Broquetas Ibars, Antoni; González Arbesú, José María; Closa Domínguez, Josep M.; Labriola, M (2011-09-15)
