    The first-ever dual-frequency multi-constellation Global Navigation Satellite Systems Reflectometry (GNSS-R) polarimetric measurements over boreal forests and lakes from the stratosphere are presented. Data were collected ...
  • Ground-based polarimetric SAR interferometry for the monitoring of terrain displacement phenomena-part I: theoretical description 

    Iglesias González, Rubén; Aguasca Solé, Alberto; Fabregas Canovas, Francisco Javier; Mallorquí Franquet, Jordi Joan; Monells Miralles, Daniel; López Martínez, Carlos; Pipia, Luca (2015-03-01)
    Article
    Open Access
    Ground-based synthetic aperture radar (SAR) (GB-SAR) sensors represent an effective solution for the monitoring of ground displacement episodes. Initially, the most GB-SAR sensors were based on vector network analyzers ...
  • Multi-wavelength aerosol LIDAR signal pre-processing: practical considerations 

    Rodríguez Gómez, Alejandro Antonio; Rocadenbosch Burillo, Francisco; Sicard, Michaël; Lange, Diego; Barragán Cuesta, Rubén; Batet Torrell, Oscar; Comerón Tejero, Adolfo; López Márquez, Miguel Ángel; Muñoz Porcar, Constantino; Tiana Alsina, Jordi; Tomás Martínez, Sergio (2015-12)
    Article
    Open Access
    Elastic lidars provide range-resolved information about the aerosol content in the atmosphere. Nevertheless, a number of pre-processing techniques need to be used before performing the inversion of the detected signal: ...
  • Numerical computation of the electromagnetic bias in GNSS-R altimetry 

    Ghavidel, Ali; Schiavulli, Domenico; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2016-01-01)
    Article
    Open Access
    In radar altimetry, the electromagnetic (EM) bias is originated by the smaller reflectivity of wave crests than troughs; thus, the average sea surface height is underestimated. Bias uncertainty is currently the largest ...
  • Retrieval of significant wave height and mean sea surface level using the GNSS-R interference pattern technique: results from a three-month field campaign 

    Alonso Arroyo, Alberto; Camps Carmona, Adriano José; Hyuk, Park; Pascual Biosca, Daniel; Onrubia Ibáñez, Raúl; Martín Alemany, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2015-06-01)
    Article
    Open Access
    Since 1993, when the European Space Agency (ESA) proposed the use of Global Navigation Satellite Systems reflected signals for sea mesoscale altimetry, a wide range of applications have appeared. This paper focuses on the ...
  • Local isotropy indicator for SAR image filtering: application to Envisat/ASAR images of the Doñana Wetland 

    Martí Cardona, Belén; López Martínez, Carlos; Dolz Ripollès, Josep (2015-04)
    Article
    Open Access
    This paper explores a geometrical and computationally simple operator, named Ds, for local isotropy assessment on SAR images. It is assumed that isotropic intensity distributions in natural areas, either textured or ...
  • Performance analysis of satellite-to-ground downlink optical communications with spatial diversity over Gamma–Gamma atmospheric turbulence 

    Li, Kanging; Ma, Jing; Belmonte Molina, Aniceto; Tan, Liying; Yu, Siyuan (2015-12-08)
    Article
    Restricted access - publisher's policy
    The performances of satellite-to-ground downlink optical communications over Gamma–Gamma distributed turbulence are studied for a multiple-aperture receiver system. Equal gain-combining (EGC) and selection-combining (SC) ...
  • EARLINET: potential operationality of a research network 

    Sicard, Michaël; D'Amico, Giuseppe; Comerón Tejero, Adolfo; Mona, Lucia; Alados Arboledas, Lucas; Amodeo, Aldo; Baars, Holger; Baldasano Recio, José María; Belegante, Livio; Binietoglou, Ioannis; Bravo Aranda, Juan Antonio; Fernández García, Alfonso; Fréville, Patrick; García Vizcaíno, David; Giunta, Aldo; Granados Muñoz, Maria; Guerrero Rascado, Juan Luis; Hadjimitsis, D.; Haefele, A.; Hervo, M.; Iarlori, M.; Kokkalis, P; Lange Vega, Diego; Mamouri, Rodanthi-Elisavet; Mattis, Ina; Molero, Francisco; Montoux, Nadège; Muñoz, Alvaro; Muñoz Porcar, Constantino; Navas Guzmán, Francisco; Nicolae, D.; Nisantzi, A.; Papagiannopoulos, N.; Papayannis, Alexander; Pereira, Sérgio; Preissler, Jana; Pujadas Cordero, Manuel; Rizi, Vicenzo; Rocadenbosch Burillo, Francisco; Sellegri, Karine; Simeonov, Valentin; Tsaknakis, G.; Wagner, Frank; Pappalardo, Gelsomina (2015-11-02)
    Article
    Open Access
    In the framework of ACTRIS (Aerosols, Clouds, and Trace Gases Research Infrastructure Network) summer 2012 measurement campaign (8 June–17 July 2012), EARLINET organized and performed a controlled exercise of feasibility ...
  • Time-domain statistics of the electromagnetic bias in GNSS-reflectometry 

    Ghavidel, Ali; Camps Carmona, Adriano José (2015-09-01)
    Article
    Open Access
    Global Navigation Satellite Systems-Reflectometry (GNSS-R) is an emerging remote sensing technique that uses navigation signals reflected on the Earth's surface as sources of opportunity for scatterometry and altimetry. ...
  • Measurement of flow vorticity with helical beams of light 

    Belmonte Molina, Aniceto; Rosales Guzmán, Carmelo; Torres, Juan P. (Optical Society of American (OSA), 2015-11-20)
    Article
    Open Access
    It is possible to devise an experiment in which the local vorticity of a flow can be estimated by probing the fluid with Laguerre–Gauss (LG) beams, i.e., optical beams that show an azimuthal phase variation that is the ...
