      Conference report
      Open Access
      This paper describes the design and construction of a bistatic SAR receiver suitable for airborne applications, using orbital SAR systems (ENVISAT, ERS-2, RADARSAT, TerraSAR-X among others) as opportunity transmitters. The ...
    • Application of TerraSAR-X data to the monitoring of urban subsidence in the city of Murcia 

      Mulas, Joaquín; Navarro Sánchez, Victor D.; Vicente, Fernando; Monells Miralles, Daniel; Centolanza, Giuseppe; Mallorquí Franquet, Jordi Joan; Duque Biarge, Sergio; López Dekker, Francisco J.; Tomás, Roberto; Herrera, Gerardo; López-Sánchez, Juan Manuel (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
      Conference report
      Open Access
      This paper presents an analysis of the performance of TerraSAR-X for subsidence monitoring in urban areas. The city of Murcia has been selected as a test-site due to its high deformation rate and the set of extensometers ...

      Duque Biarge, Sergio; López Dekker, Francisco J.; Merlano Duncan, Juan Carlos; Mallorquí Franquet, Jordi Joan (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
      Conference report
      Open Access
      This paper presents an along-track interferometry (ATI)study for a bistatic or multiestatic SAR configuration with fixed ground receivers. This technique can be useful for sea current estimation or for any problem of Ground ...
    • Bistatic SAR tomography: processing and experimental results 

      Duque Biarge, Sergio; López Dekker, Francisco J.; Merlano Duncan, Juan Carlos; Mallorquí Franquet, Jordi Joan (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
      Conference report
      Open Access
      This paper presents across-track tomography applied to a bistatic geometry with fixed receivers. This kind of geometry can overcome some of the classical monostatic tomography limitations such as temporal decorrelation and ...
    • Capon- and APES-based SAR processing: performance and practical considerations 

      López Dekker, Francisco J.; Mallorquí Franquet, Jordi Joan (IEEE Press. Institute of Electrical and Electronics Engineers, 2010-05)
      Article
      Open Access
      This paper discusses the use of Capon’s minimumvariance method (MVM) and Amplitude and Phase EStimation (APES) spectral-estimation algorithms to synthetic aperture radar range–azimuth focusing. The rationale of the ...
