    • Development and implementation of an adaptive digital beamforming network for satellite communication systems 

      Barrett, M; Fernández Rubio, Juan Antonio (1991-09)
      Article
      Accés obert
      The use of adaptive digital beamforming techniques has, until recently, been largely restricted to high performance military radar systems. Recent advances in digital technology, however, have enabled the design of single ...

    • High performance doa trackers derived from paralell low resolution detectors 

      Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (IEEE, 1996)
      Text en actes de congrés
      Accés obert
      Traditionally, high resolution spectral direction of arrival (DOA) estimation has been associated with algorithms rather than with a processing scheme or architecture. Motivated by previous work on feasible implementations ...

    • Hybrid sparse linear array synthesis applied to phased antenna arrays 

      Yepes, Leonardo Fabio; Covarrubias, David; Alonso, Miguel A.; Ferrús Ferré, Ramón Antonio (2014-01-16)
      Article
      Accés restringit per política de l'editorial
      In this letter, a new hybrid technique to synthesize sparse linear arrays is proposed. This technique is based on the combination of two methods. As a first method, a deterministic synthesis algorithm is used to resolve ...

    • Pointing correction in an adaptive array for communications 

      Lagunas Hernandez, Miguel A.; Nájar Martón, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 1991)
      Text en actes de congrés
      Accés obert
      The authors discuss DSP procedures for pointing correction in adaptive arrays which uses a spatial reference to form the optimum beam (generalized sidelobe canceller, GSLC). The problem of adequate pointing arises from ...
