Absorption spectroscopy with quantum light: experimental and theoretical simulations based on arbitrary spectral shapes generated with a programable filter
(Universitat Politècnica de Catalunya, 2023-09-06)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Institut de Ciències Fotòniques (ICFO)Absorption spectroscopy is a useful technique to detect the presence of specific elements in samples. However, its usefulness can be severely limited in certain frequency bands due to technological limitations, such as the ... -
Automatic calibration of channels frequency response in interferometric radiometers
(IEE-INST ELEC ENG, 1999-01-31)
Article
Accés obertThe large field of view required in Earth observation interferometric radiometers does not enable the use of a variable delay to compensate for different transit times, as in radioastronomy. A technique is presented to ... -
Forbush decreases and <2 day GCR flux non-recurrent variations studied with LISA pathfinder
(Institute of Physics (IOP), 2019-04-01)
Article
Accés obertNon-recurrent short-term variations of the galactic cosmic-ray (GCR) flux above 70 MeV n-1 were observed between 2016 February 18 and 2017 July 3 on board the European Space Agency LISA Pathfinder (LPF) mission orbiting ... -
Fundamental limits of phase estimation with nonlinear interferometers
(Universitat Politècnica de Catalunya, 2022-09-09)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Universitat de Barcelona / Universitat Autònoma de BarcelonaInterferometers have established themselves as good phase sensitivity estimators, although passive interferometers (those characterized by the SU(2) group) are bounded by the shot noise limit. If we want to overcome this ... -
GEOSAR permanent continental observation. Impact of atmospheric and surface decorrelation
(Universitat Politècnica de Catalunya, 2021-07-08)
Projecte Final de Màster Oficial
Accés restringit per acord de confidencialitatEarth Observation missions are usually carried out by Low-Earth Orbit (LEO) satellites, which have major drawbacks when it comes to continuous monitoring of certain aspects of the Earth. The European Space Agency is currently ... -
Improvement of SMOS radiometric accuracy for salinity retrieval applications
(Universitat Politècnica de Catalunya, 2016-07-13)
Treball Final de Grau
Accés obertThis Degree Thesis has been performed at the Remote Sensing Laboratory (RSLab), at the Department of Signal Theory and Communications of the Universitat Politècnica de Catalunya. It consists on a set of strategies devoted ... -
Multi-stroke positive cloud-to-ground lightning sharing the same channel observed with a VHF broadband interferometer
(2022-04-15)
Article
Accés obertIn the same lightning flash, whose usual duration is less than a second, there can be multiple negative cloud-to-ground strokes with different terminations or following a preexisting channel to the ground. In contrast, it ... -
New interferometric label-free biosensing system for food allergy diagnostics in biophotonic sensing cells

On the detection of RFI through the correlation anomaly at different time lags
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Text en actes de congrés
Accés obertMicrowave radiometers can be considerably affected by Radio Frequency Interference (RFI). These man-made interference conceal the underlying natural signal, preventing the retrieval of geophysical variables. Adopting ... -
