  • 94 GHz pulsed coherent radar for high power amplifier evaluation 

    Robertson, Duncan Alexander; Hunter, Robert Iain; Gallacher, Thomas (SPIE-The International Society for Optical Engineering, 2016-05-12) - Conference item
    We present the design and characterization of a 94 GHz pulsed coherent radar to be used for the evaluation and demonstration of novel wideband, high power vacuum tube amplifier technology. The radar is designed to be fully ...
  • Millimeter wave imaging at up to 40 frames per second using an optoelectronic photo-injected Fresnel zone plate lens antenna 

    Robertson, Duncan Alexander; Gallacher, Thomas; Sondena, Rune; Macfarlane, David Graham (SPIE-The International Society for Optical Engineering, 2016-05-12) - Conference item
    Optoelectronic methods are promising for rapid and highly reconfigurable beam steering across the microwave to the terahertz range. In particular, the photo-injected Fresnel zone plate antenna (piFZPA) offers high speed, ...
  • Millimetre-wave FMCW radar for remote sensing and security applications 

    Cassidy, Scott L. (University of St Andrews, 2015-11-30) - Thesis
    This thesis presents a body of work on the theme of millimetre-wave FMCW radar, for the purposes of security screening and remote sensing. First, the development of an optimised software radar signal processor will be ...
  • Second generation of AVTIS FMCW millimeter wave radars for mapping volcanic terrain 

    MacFarlane, David Graham; Robertson, Duncan Alexander; Cassidy, Scott Lindsay (SPIE-The International Society for Optical Engineering, 2016-05-12) - Conference item
    The second generation AVTIS ground-based millimeter wave instruments designed for monitoring topography of volcanic lava domes are solid state 94 GHz FMCW rastered, real beam radars operating at ranges of up to ~7 km with ...
  • Techniques for homodyne dechirp-on-receive linearly frequency modulated radar 

    Middleton, Robert (University of St Andrews, 2011-06-22) - Thesis
    This thesis presents work done to extend and improve the operation of homodyne dechirp-on-receive linearly frequency modulated radars. First, an investigation of the effect of common phase errors on the point response ...
