Contribution to the application of near ground L-band radiometry
(Universitat Politècnica de Catalunya, 2019-07-16)
Projecte Final de Màster Oficial
Accés obertARIEL is an L-band radiometer adapted from Earth Observation satellite technology for use in terrestrial, near to ground surveys of moisture. The key technical benefits are compact size, lightweight, mobility and high pixel ... -
Design of a deployable helix antenna at L-Band for a 1-Unit CubeSat: from theoretical analysis to flight model results
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-01)
Article
Accés obertThe 3Cat-4 mission aims at demonstrating the capabilities of a CubeSat to perform Earth Observation (EO) by integrating a combined GNSS-R and Microwave Radiometer payload into a 1-Unit CubeSat. One of the greatest challenges ... -
Sea state effect on the sea surface emissivity at L-band

(Universitat Politècnica de Catalunya, 2009-02-27)
Projecte/Treball Final de Carrera
Accés obertThis work project will be divided in 5 chapters. Firstly, chapter two reviews the basics of radiometry, emission theory and types of radiometer. Chapter three covers the avionic system in place aboard the platform, ... -
Study of radio frequency interference effects on radiometry bands in urban environments
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Text en actes de congrés
Accés restringit per política de l'editorialMicrowave radiometers are very accurate passive sensors that have been successfully used in Earth remote sensing during the last decades. Microwave radiometers measure thermal noise, therefore any other signal (radio-frequency ... -
The light airborne reflectometer for GNSS-R observations (LARGO) instrument: initial results from airborne and Rover field campaigns
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialGlobal Navigation Satellite Systems (GNSS)-Reflectometry (GNSS-R) has proved to be a useful technique for the estimation of Soil Moisture (SM). In the past 10 years, different techniques such as the Interference Pattern ... -
