    • Completion and decomposition of a clutter into representable matroids 

      Martí Farré, Jaume; Mier Vinué, Anna de (Elsevier, 2015-05-01)
      Article
      Accés obert
      This paper deals with the question of completing a monotone increasing family of subsets Gamma of a finite set Omega to obtain the linearly dependent subsets of a family of vectors of a vector space. Specifically, we prove ...

    • From clutters to matroids 

      Fàbrega Canudas, José; Martí Farré, Jaume; Muñoz López, Francisco Javier (Universidad de Sevilla, 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper deals with the question of completing a monotone increasing family of subsets to obtain the dependent sets of a matroid. More precisely, we provide several natural ways of transforming the clutter of the inclusion ...

    • Impact of scene decorrelation on geosynchronous SAR data focusing 

      Recchia, Andrea; Monti Guarnieri, Andrea; Broquetas Ibars, Antoni; Leanza, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2016-03-01)
      Article
      Accés obert
      We discuss the effects of the clutter on geosynchronous SAR systems exploiting long integration times (from minutes to hours) to counteract for two-way propagation losses and increase azimuth resolution. Only stable targets ...

    • Linearly dependent vectorial decomposition of clutters 

      Martí Farré, Jaume (2014)
      Text en actes de congrés
      Accés obert
      This paper deals with the question of completing a monotone increas- ing family of subsets G of a finite set ¿ to obtain the linearly dependent subsets of a family of vectors of a vector space. Specifically, we demonstrate ...

    • Simulació estadística de clutter marí amb models de distribució K 

      González Moragas, Oriol (Universitat Politècnica de Catalunya, 2011-09-07)
      Projecte/Treball Final de Carrera
      Accés obert
      English: The aim of this project is the simulation of the radar echo signal scattered by the sea surface which is called "Sea clutter". This project is related with the SAR MTI systems which are a type of radar systems ...

    • Transformation and decomposition of clutters into matroids 

      Martí Farré, Jaume; Mier Vinué, Anna de (2017-05-25)
      Article
      Accés obert
      A clutter is a family of mutually incomparable sets. The set of circuits of a matroid, its set of bases, and its set of hyperplanes are examples of clutters arising from matroids. In this paper we address the question of ...
