Forte Véliz, Giuseppe Francesco (Data de defensa: 2014-06-26)
Radio Frequency Interference (RFI) is the most common problem for electronic measuring systems. The presence of those electromagnetic waves can harm the measurements taken from very sensitive instruments, ...
Ghavidel, Ali (Data 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 ...
Piles Guillem, Maria (Data de defensa: 2010-07-16)
La humedad del suelo es la variable que regula los intercambios de agua, energía, y carbono entre la tierra y la atmósfera. Mediciones precisas de humedad son necesarias para una gestión sostenible de ...
Martín Alemany, Francisco (Data 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 ...
Querol Borràs, Jorge (Data de defensa: 2018-11-09)
Radio-Frequency Interference (RFI) signals are undesired signals that degrade or disrupt the performance of a wireless receiver. RFI signals can be troublesome for any receiver, but they are especially ...
Bosch Lluis, Xavier (Data de defensa: 2011-03-30)
Actualment, la comunitat científica ja disposa de les primeres mesures radiomètriques a banda L, polarimètriques i multi-angulars fetes de l’espai. Això és gràcies al recent llançament de la missió de ...
Ramos Pérez, Isaac (Data de defensa: 2012-02-27)
The Soil Moisture and Ocean Salinity (SMOS) mission is an Earth Explorer Opportunity mission from the European Space Agency (ESA). It was a direct response to the global observations of soil moisture ...
Valencia Domènech, Enric (Data de defensa: 2012-10-17)
The knowledge of sea surface salinity (SSS) is a key issue to understand and monitor the Earth¿s water cycle. Accurate and systematic measurement of SSS was not possible until the ESA¿s Soil Moisture ...
Jové Casulleras, Roger (Data de defensa: 2015-02-17)
The submitted Ph.D. thesis is a contribution to the development of pico-satellites and nano-satellites for Earth Observation and Technology Demonstrators. Development of satellites with a mass from 1 ...
Tarongí Bauzá, José Miguel (Data de defensa: 2013-03-06)
Microwave radiometry field has been increasing its performance with higher accuracy measurements, leading to a more presence in the remote sensing field. Several space-borne, air-borne and ground-based ...
