    Aplicación de UAVS a la detección de fauna como soporte a los censos cinegéticos. REDIAM
    (Editorial Universitat Politècnica de València, 2014-06-24) Prieto Molina, R.; Méndez, E.; Vales, J.J.; Pino, I.; Carpintero, I.R.; Granado, L.; Montoya, G.; Giménez de Azcárate, F.; Cáceres, F.; Moreira, J.M.
    [EN] The following paper details the methodology for analyzing the potential of Unmanned Aerial Vehicles (UAV) as suitable observation platforms for obtaining thermal images of hunting areas, and for the estimation of number of individuals for these populations (fauna, in this case deer). Due to limitations detected in the initial information, some of the work stages are alternative approaches to an optimal process. On this basis, specific technical flight requirements are proposed in order to carry out a more appropriate analysis.

    Misión FLEX (Fluorescence Explorer): Observación de la fluorescencia por teledetección como nueva técnica de estudio del estado de la vegetación terrestre a escala global
    (Editorial Universitat Politècnica de València, 2014-06-24) Moreno, J.; Alonso, L.; Delegido, J.; Rivera, J.P.; Ruiz-Verdú, A.; Sabater, N.; Tenjo, C.; Verrelst, J.; Vicent, J.; Ministerio de Ciencia e Innovación
    [EN] FLEX (Fluorescence EXplorer) is a candidate for the 8th ESA’s Earth Explorer mission. Is the first space mission specifically designed for the estimation of vegetation fluorescence on a global scale. The mission is proposed to fly in tandem with the future ESA´s Sentinel-3 satellite. It is foreseen that the information obtained by Sentinel-3 will be supplemented with that provided by FLORIS (Fluorescence Imaging Spectrometer) onboard FLEX. FLORIS will measure the radiance between 500 and 800 nm with a bandwidth between 0.1 nm and 2 nm, providing images with a 150 km swath and 300 m pixel size. This information will allow a detailed monitoring of vegetation dynamics, by improving the methods for the estimation of classical biophysical parameters, and by introducing a new one: fluorescence. This paper presents the current status of FLEX mission in A/B1 phase and the different ongoing studies, campaigns and projects carried out in support of the FLEX mission.

    Explotación científica de productos PAZ en tareas de vigilancia y monitorización costera
    (Editorial Universitat Politècnica de València, 2014-06-24) Jarabo Amores, M.P.; González Bonilla, M.J.; Mata Moya, D. de la; Martín de Nicolás Presa, J.; Rey Maestre, N. del; Bárcena Humanes, J.L.; Peláez Sánchez, V.M.
    [EN] PAZ mission appears due to the need of a Spanish SAR satellite able to provide radar image products for security and defense, civil and scientific users. INTA is responsible for the technical direction of the Ground Segment, as well as the development of the Calibration and Validation Centre and the scientific exploitation. The ‘Demonstrator of Maritime SAR Applications’ is proposed as an answer to detection tasks in maritime synthetic aperture radar imagery, which are not completely solved yet. DeMSAR has been developed in the framework of a contract between the Spanish National Institute for Aerospace Technology (INTA) and the University of Alcalá. It is intended to be used as a demonstrator of the capabilities of the airborne SAR prototypes of INTA as well as for PAZ, the Spanish SAR satellite. With two operation modes, an automatic ship detector and a toolboxes mode, DeMSAR offers the user a high flexibility in SAR data processing tasks such as speckle filtering, coastline detection, land mask estimation and ship detection and characterization.

    RBX: El nuevo radar SAR en banda X del INTA
    (Editorial Universitat Politècnica de València, 2014-06-24) Larrañaga, J.R.; de Porras, R.; del Castillo, J.; Gimeno, N.; Aguilar, P.; Baquero, A.M.; Casal, N.; Cifuentes, P.; Cores, J.F.; Cuerda, J.M.; García, M.; Gómez, B.; González, M.J.; López, A.; Madroño, D.; Ojalvo, L.; Pedreira, A.; Sánchez, S.
    [EN] This paper describes the characteristics and the first results of the RBX system, the new airborne Synthetic Aperture Radar developed at Spanish National Institute of Aerospace Technology. The new system supports submetric resolution with interferometric and polarimetric capabilities. The system architecture has been designed taking into account an easy upgrade ability and the quality of the acquired data, including multiple internal calibration loops.

    El radiómetro de microondas MWR de Sentinel-3: Nuestra contribución al éxito de Copernicus
    (Editorial Universitat Politècnica de València, 2014-06-24) Palacios, M.A.; Bergadà, M.; González, R.; Gamonal, A.; García-Fernández, J.L.; Camacho, Y.
    [EN] The MWR builds, together with the SRAL altimeter, the S3 topography mission. The MWR, developed by EADS CASA Espacio as prime contractor, provides information for tropospheric path correction of SRAL measurements. MWR data can also be used for determining surface emissivity and soil moisture over land, surface energy budget investigations and ice characterization. The MWR instrument is a Noise Injection Radiometer (NIR), working at two frequencies (23.8/36.5 GHz), embarking a dual frequency horn antenna pointing to the cold sky for embedded autonomous calibration.
