    • Adaptive Digital Beam-Forming for High-Resolution Wide-Swath Synthetic Aperture Radar 

      Makhoul Varona, Eduardo (Universitat Politècnica de Catalunya, 2009-06-29)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   Deutsches Zentrum für Luft-und Raumfahrt
      The thesis “Adaptive Digital Beam-Forming for High-Resolution Wide-Swath Synthetic Aperture Radar” is a project carried out in the Microwaves and Radar Institute (IHR) at the German Aerospace Center (DLR) The objective ...

    • Atmospheric turbulence profile modeling for satellite-ground laser communication 

      Otoniel Canuet, Lucien François (Universitat Politècnica de Catalunya, 2015-07-23)
      Master thesis
      Open Access
      Covenantee:   Deutsches Zentrum für Luft-und Raumfahrt
      The major limitation of free-space laser communications' performances is due to atmospheric turbulence. Free-space optical channels are characterized by a set of different parameters such as the scintillation index, the ...

    • Coupling strategies for solving the RANS equations 

      Suárez Martínez, Guillermo (Universitat Politècnica de Catalunya, 2020-02-14)
      Master thesis
      Open Access
      Covenantee:   Deutsches Zentrum für Luft-und Raumfahrt
      For the present work two implicit methods of coupling the compressible Reynolds Averaged Navier-Stokes equations in conjunction with the one equation Spalart-Allmaras turbulence model have been developed. The first approach, ...

    • Flight Test Preparation of a 4D-controller for time constrained Continous Descent Operations (CDO) 

      Bendris, Bianca Mihaela (Universitat Politècnica de Catalunya, 2015-09-09)
      Bachelor thesis
      Open Access
      Covenantee:   Deutsches Zentrum für Luft-und Raumfahrt
      Within the Clean Sky European project, a flight test prepared by the German Aerospace Center (DLR) is foreseen and meant to prove the capability of flying a Continous Descent Operation (CDO) while satisfying a time constraint ...

    • Machine learning for packet detection in satellite communications 

      Simon Campreciós, Pol (Universitat Politècnica de Catalunya, 2025-02-10)
      Master thesis
      Open Access
      Covenantee:   Deutsches Zentrum für Luft-und Raumfahrt
      Satellite-based IoT networks demand efficient and robust short-packet detection techniques, particularly in Low Earth Orbit (LEO) scenarios where devices operate with low power and transmit sporadically. This thesis explores ...

    • Real-time vehicle speed estimation using Unmanned Aerial Vehicles for traffic surveillance 

      Saíz Vázquez, David (Universitat Politècnica de Catalunya, 2023-09-14)
      Bachelor thesis
      Open Access
      Covenantee:   Deutsches Zentrum für Luft-und Raumfahrt
      Drones are an emerging tool for traffic surveillance; however, they inherently lack the capability to solely obtain vehicle speed on the road. This Bachelor's thesis presents the design, implementation and study of a system ...

    • Validation using performance reference data of an Airbus A320 performance model for flight simulation 

      Sáez García, Raúl (Universitat Politècnica de Catalunya, 2015-10-29)
      Bachelor thesis
      Open Access
      Covenantee:   Deutsches Zentrum für Luft-und Raumfahrt
      The aim of this project is to improve the performance model of the QPAC (QualityPark AviationCenter) A320 in X-Plane flight simulator. In order to achieve it, tables generated with Airbus PEP (Performance Engineering Program ...
