Onrubia Ibáñez, Raúl (Fecha de defensa: 2020-03-13)
This work is the result of more than eight years during a bachelor thesis, a master thesis, and the Ph.D. thesis dedicated to the development of the Microwave Interferometric Reflectometer (MIR) instrument. It summarizes ...
Muñoz Porcar, Constantino (Fecha de defensa: 2013-02-22)
This thesis is the initial stage in the development of a range-resolving Doppler wind lidar. Atmospheric lidars emit pulsed laser radiation that after being scattered by air molecules and suspended aerosol particles is ...
Tessitore, Serena (Fecha de defensa: 2014-05-09)
The aim of the present thesis has been to test the applicability of the innovative Advanced DInSAR techniques in the natural risk mitigation related to subsidence phenomena. In particular, two test sites have been chosen, ...
Anzuola Valencia, Esdras (Fecha de defensa: 2015-06-15)
In the last years free-space optical communications systems for wireless links have been proposed, studied, and implemented mainly due to the higher bandwidth that this technology is able to provide. Still, radio frequency ...
Saeed, Umar (Fecha de defensa: 2016-07-22)
The Atmospheric Boundary Layer Height (ABLH) is an important parameter in weather forecasting, meteorology, avionics, and air-quality and dispersion models. Local development of the Atmospheric Boundary Layer (ABL) over ...
Alonso Arroyo, Alberto (Fecha de defensa: 2016-11-10)
This PhD thesis researches the use of passive remote sensing techniques using signals transmitted from the navigation satellites (GNSS) in order to retrieve different geophysical parameters. The thesis consists of two ...
Ghavidel, Ali (Fecha de defensa: 2015-07-14)
In this Ph. D. dissertation the electromagnetic bias in GNSS-R (Global Navigation Satellite Systems Reflectometry) altimetry has been studied. GNSS-R altimetry is a new type of system that uses navigation signals as signals ...
Pascual Biosca, Daniel (Fecha de defensa: 2020-12-21)
GNSS reflectometry (GNSS-R) is a set of techniques that uses the reflected GNSS signals over the Earth’s surface as opportunity signals for remote sensing applications. In 1993, the European Space Agency (ESA) suggested ...
Muñoz Martin, Joan Francesc (Fecha de defensa: 2021-06-17)
Earth Observation using satellites has helped to better model our planet. The goal of such systems is to provide large data sets to help to understand the effects of our actions on the climate, to predict storms in near ...
Pons Freixes, Sergi (Fecha de defensa: 2016-01-28)
Water is the most important resource for living on planet Earth, covering more than 70% of its surface. The oceans represent more than 97% of the planet total water and they are where more than the 99.5% of the living ...
Egido Egido, Alejandro (Fecha de defensa: 2013-07-05)
Soil moisture and vegetation biomass are two essential parameters from a scienti c and economical point of view. On one hand, they are key for the understanding of the hydrological and carbon cycle. On the other hand, soil ...
Fabra Cervellera, Francisco (Fecha de defensa: 2013-05-13)
This work evaluates the potential use of signals from the Global Navigation Satellite Systems (GNSS) that scatter off the Earth surface for the retrieval of geophysical information from the cryosphere. For this purpose, ...
Devanthéry Arasa, Núria (Fecha de defensa: 2014-10-31)
Persistent Scatterer Interferometry (PSI) is a group of advanced differential interferometric SAR techniques that are used to measure and monitor terrain deformation. Different PSI techniques have been proposed in the last ...
Martín Alemany, Francisco (Fecha de defensa: 2015-07-14)
This PhD dissertation is focused on the use of the opportunity signals from the Global Navigation Satellite Systems (GNSS), that scatter-off the Earth's surface for perform ocean mesoscale altimetry (the so called GNSS-R ...
Lange Vega, Diego (Fecha de defensa: 2014-07-17)
This Ph.D. thesis addresses remote sensing of the atmosphere by means of lidar and S-band clear-air weather radar, and related data signal processing. Active remote sensing by means of these instruments offers unprecedented ...
González Haro, Cristina (Fecha de defensa: 2015-05-22)
Ocean currents are a key component to understanding many oceanic and climatic phenomena and knowledge of them is crucial for both navigation and operational applications. Therefore, a key problem in oceanography is the ...
