      This paper presents a comparative study of the radiometric sensitivity and spatial resolution of three near-field (NF) passive screener systems: real aperture, 1-D synthetic aperture (SA), and 2-D SA radiometers are compared. ...
    • Retina design for 100GHz MST imaging system 

      Alonso, Maria; Garg, V.; Nova, Enrique; Abril, Jordi; Romeu Robert, Jordi; Llombart, Nuria; Jofre Roca, Lluís (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A near field imaging system for THz tomographic imaging based on a MST retina (an array of real antennas) has been designed. The main adva ntage of this implementation is the absence of microwave transmission line ...
    • Teraherz subsurface imaging system 

      Nova, Enrique; Abril, Jordi; Guardiola Garcia, Marta; Capdevila Cascante, Santiago; Broquetas Ibars, Antoni; Romeu Robert, Jordi; Jofre Roca, Lluís (2010)
      Text en actes de congrés
      Accés obert
      A subsurface imaging system based on a terahertz time-domain spectrometer (THz-TDS) is described in this paper. The system performance has been simulated in terms of spatial resolution, penetration capabilities and SNR. ...
    • The “challenging” world of Terahertz radiation and imaging 

      Jofre Roca, Lluís; Romeu Robert, Jordi; Capdevila Cascante, Santiago; Abril, Jordi; Nova, Enrique; Alonso, Maria (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      THz propagation through materials may reveal unique macroscopic and physical properties of their internal structure without the damage associated with ionizing radiation. The generation, radiation, and detection of THz ...
    • W-band radiometric imager with mechanical beam-scanning 

      Nova, Enrique; Abril, Jordi; Romeu Robert, Jordi; Broquetas Ibars, Antoni; Torres Torres, Francisco; Jofre Roca, Lluís (IEEE, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The design of a 94 GHz Total Power Radiometer system for imaging purposes is presented in this paper. A mechanical beam-scanning antenna system is used to acquire passive raster images. The main performance parameters ...
