Adaptive Digital Beam-Forming for High-Resolution Wide-Swath Synthetic Aperture Radar
(Universitat Politècnica de Catalunya, 2009-06-29)
Master thesis (pre-Bologna period)
Open Access
Covenantee: Deutsches Zentrum für Luft-und RaumfahrtThe 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
(Universitat Politècnica de Catalunya, 2015-07-23)
Master thesis
Open Access
Covenantee: Deutsches Zentrum für Luft-und RaumfahrtThe 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
(Universitat Politècnica de Catalunya, 2020-02-14)
Master thesis
Open Access
Covenantee: Deutsches Zentrum für Luft-und RaumfahrtFor 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)
(Universitat Politècnica de Catalunya, 2015-09-09)
Bachelor thesis
Open Access
Covenantee: Deutsches Zentrum für Luft-und RaumfahrtWithin 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
(Universitat Politècnica de Catalunya, 2025-02-10)
Master thesis
Open Access
Covenantee: Deutsches Zentrum für Luft-und RaumfahrtSatellite-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
(Universitat Politècnica de Catalunya, 2023-09-14)
Bachelor thesis
Open Access
Covenantee: Deutsches Zentrum für Luft-und RaumfahrtDrones 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
(Universitat Politècnica de Catalunya, 2015-10-29)
Bachelor thesis
Open Access
Covenantee: Deutsches Zentrum für Luft-und RaumfahrtThe 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 ...
