    • Forbush decreases and <2 day GCR flux non-recurrent variations studied with LISA pathfinder 

      Armano, M.; Audley, H.; Baird, J.; Benella, S.; Binetruy, P.; Born, M.; Bortoluzzi, D.; Ramos Castro, Juan José (Institute of Physics (IOP), 2019-04-01)
      Article
      Accés obert
      Non-recurrent short-term variations of the galactic cosmic-ray (GCR) flux above 70 MeV n-1 were observed between 2016 February 18 and 2017 July 3 on board the European Space Agency LISA Pathfinder (LPF) mission orbiting ...

    • Fundamental limits of phase estimation with nonlinear interferometers 

      Pérez Castro, David (Universitat Politècnica de Catalunya, 2022-09-09)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Universitat de Barcelona / Universitat Autònoma de Barcelona
      Interferometers have established themselves as good phase sensitivity estimators, although passive interferometers (those characterized by the SU(2) group) are bounded by the shot noise limit. If we want to overcome this ...

    • GEOSAR permanent continental observation. Impact of atmospheric and surface decorrelation 

      Palacio García, Héctor (Universitat Politècnica de Catalunya, 2021-07-08)
      Projecte Final de Màster Oficial
      Accés restringit per acord de confidencialitat
      Earth Observation missions are usually carried out by Low-Earth Orbit (LEO) satellites, which have major drawbacks when it comes to continuous monitoring of certain aspects of the Earth. The European Space Agency is currently ...

    • Improvement of SMOS radiometric accuracy for salinity retrieval applications 

      Vizcarro I Carretero, Marc (Universitat Politècnica de Catalunya, 2016-07-13)
      Treball Final de Grau
      Accés obert
      This Degree Thesis has been performed at the Remote Sensing Laboratory (RSLab), at the Department of Signal Theory and Communications of the Universitat Politècnica de Catalunya. It consists on a set of strategies devoted ...

    • Multi-stroke positive cloud-to-ground lightning sharing the same channel observed with a VHF broadband interferometer 

      Urbani, Michele; Montañá Puig, Juan; Van der Velde, Oscar Arnoud; Sousa Arcanjo, Marcelo Augusto; López Trujillo, Jesús Alberto (2022-04-15)
      Article
      Accés obert
      In the same lightning flash, whose usual duration is less than a second, there can be multiple negative cloud-to-ground strokes with different terminations or following a preexisting channel to the ground. In contrast, it ...

    • New interferometric label-free biosensing system for food allergy diagnostics in biophotonic sensing cells 

      López Espinosa, Rocío; Garrido Arandia, María; Romero Sahagún, Alejandro; Herreros, P.; Tramarin, L.; Laguna, M. F.; Díaz Perales, Araceli; Holgado Bolaños, Miguel (2021-05-13)

    • On the detection of RFI through the correlation anomaly at different time lags 

      Díez García, Raúl; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Text en actes de congrés
      Accés obert
      Microwave radiometers can be considerably affected by Radio Frequency Interference (RFI). These man-made interference conceal the underlying natural signal, preventing the retrieval of geophysical variables. Adopting ...
