    This article presents an intercomparison between four different ROMTs: differential optical absorption spectroscopy (DOAS), differential absorption LIDAR (DIAL), Fourier transform infrared spectroscopy (FTIR), and tunable ...
  • Utilización de una red de estaciones UNIX para mejorar las prestaciones de un procesador SAR 

    Mallorquí Franquet, Jordi Joan; Broquetas Ibars, Antoni (European Space Agency (ESA), 1997)
    Conference report
    Open Access
    A parallel SAR processor is presented in this paper. The target configuration is a cluster of UNIX workstations, available in most user sites. This fact allows to obtain an increased computing performance w1thout the need ...

  • A pulsed carrier recovery using a discrete conception of the PLL 

    Aguasca Solé, Alberto; Broquetas Ibars, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 1992)
    Conference report
    Open Access
    A bistatic radar system requires accurate synchronization between the transmitter and the remote receiver in order to achieve a correct coherent target detection and positioning. An unlinked receiver carrier phase/frequency ...
  • A near field spherical wave inverse synthetic aperture radar technique 

    Broquetas Ibars, Antoni; Jofre Roca, Lluís; Cardama Aznar, Ángel (Institute of Electrical and Electronics Engineers (IEEE), 1992)
    Conference report
    Open Access
    The authors present an imaging near-field spherical wave inverse synthetic aperture radar (SWISAR) algorithm based on a focusing operator of the scattered fields on the target surface. A spherical wave can be easily generated ...
  • Remote bistatic receiver synchronization using DLL techniques 

    Aguasca Solé, Alberto; Broquetas Ibars, Antoni; Fernández de Muniain Comajuncosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 1992)
    Conference report
    Open Access
    Pulse to pulse staggering in the pulse reference interval (PRI), usually used to increase the radar unambiguous range and MTI blind speeds, complicates notably the synchronization of the pulsed waveform. A free running ...
  • Processing microwave experimental data with the distorted Born iterative method of nonlinear inverse scattering 

    Mallorquí Franquet, Jordi Joan; Broquetas Ibars, Antoni; PICHOT DU MEZERAY, Christian; Bolomey, Jean Charles (Institute of Electrical and Electronics Engineers (IEEE), 1993)
    Conference report
    Open Access
    The Born-iterative method (BIM) and the distorted-Born-iterative method (DBIM) have been proposed and verified as methods of solving the nonlinear inverse scattering problem for dielectric scatterers. The continuous-wave ...
  • Diseño y evaluación de un sistema de medida RCS 

    Blanch Boris, Sebastián; Xarrié, Jaume; Broquetas Ibars, Antoni; Fabregas Canovas, Francisco Javier; Jofre Roca, Lluís (Unión Científica Internacional de Radio (URSI), 1990)
    Conference report
    Open Access
    A polarimetric compact range RCS measurement system covering 8 to 40 GHZ is presented. The sensitivity is evaluated both theoretically and experimentally. Some RCS and ISAR results are included.
