    • Compressive sensing for through wall radar imaging of stationary scenes using arbitrary data measurements 

      Lagunas Targarona, Eva; Amin, Moeness G.; Ahmad, Fauzia; Nájar Martón, Montserrat (2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, we deal with removal of wall EM reflections prior to image reconstruction using step-frequency radars. The goal is to enable behind-the-wall target detection and localization from reduced data measurements. ...

    • Hybrid sparse two-dimensional antenna array synthesis using independent compression regions 

      Yepes, Leonardo Fabio; Covarrubias, David; Alonso, Miguel A.; Ferrús Ferré, Ramón Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A new approach to synthesize 2D planar antenna arrays with sparseness characteristics is presented. This approach uses a recently introduced technique called Hybrid Sparse Linear Array Synthesis (HSLAS). In order to ...

    • Spectral feature detection with Sub-Nyquist sampling for wideband spectrum sensing 

      Lagunas Targarona, Eva; Nájar Martón, Montserrat (2015-07-01)
      Article
      Accés obert
      Compressive sensing (CS) has been successfully applied to alleviate the sampling bottleneck in wideband spectrum sensing leveraging the sparsity described by the low spectral occupancy of the licensed radios. However, the ...

    • Wall mitigation techniques for indoor sensing within the compressive sensing framework 

      Lagunas Targarona, Eva; Amin, Moeness G.; Ahmad, Fauzia; Nájar Martón, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Compressive sensing (CS) for urban operations and through-the-wall radar imaging has been shown to be successful in fast data acquisition and moving target localizations. However, the research work in this area thus ...
