  • 94 GHz pulsed coherent radar for high power amplifier evaluation 

    Robertson, Duncan Alexander; Hunter, Robert Iain; Gallacher, Thomas (SPIE, 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, 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, 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 ...
  • Workshop on object recognition for input and mobile interaction 

    Yeo, Hui Shyong; Laput, Gierad; Gillian, Nicholas; Quigley, Aaron John (ACM, 2017-09-04) - Conference item
    Today we can see an increasing number of Object Recognition systems of very different sizes, portability, embedability and form factors which are starting to become part of the ubiquitous, tangible, mobile and wearable ...
