  • Bistatic 3D SAR for wall parameter extraction in cluttered environments 
    Elgy, James; Andre, Daniel; Finnis, Mark V. (IET, 2021-07-28)
    Through-wall radar is an emergent technology rooted in urban surveillance, a key component being synthetic aperture radar (SAR). Accurate through-wall SAR relies on knowledge of the refractive index and thickness of any ...
  • Explainability of deep SAR ATR through feature analysis 
    Belloni, Carole; Aouf, Nabil; Balleri, Alessio; Le Caillec, Jean-Marc; Merlet, Thomas (IEEE, 2020-10-20)
    Understanding the decision-making process of deep learning networks is a key challenge which has rarely been investigated for Synthetic Aperture Radar (SAR) images. In this paper, a set of new analytical tools is proposed ...
  • Laboratory multistatic polarimetric 3D SAR 
    Andre, Daniel; Welsh, Richard; Finnis, Mark (IET, 2023-02-07)
    With the advent of constellations of SAR satellites, and the possibility of swarms of SAR UAV's, there is increased interest in multistatic SAR image formation. This may provide advantages including allowing three-dimensional ...
  • SAR image dataset of military ground targets with multiple poses for ATR 
    Belloni, Carole; Balleri, Alessio; Aouf, Nabil; Merlet, Thomas; Le Caillec, Jean-Marc (SPIE, 2017-10-05)
    Automatic Target Recognition (ATR) is the task of automatically detecting and classifying targets. Recognition using Synthetic Aperture Radar (SAR) images is interesting because SAR images can be acquired at night and ...
  • Sidelobe suppression techniques for near-field multistatic SAR 
    Price, George A. J.; Moate, Chris; Andre, Daniel; Yuen, Peter W. T. (MDPI, 2023-01-09)
    Multirotor Unmanned Air Systems (UAS) represent a significant improvement in capability for Synthetic Aperture Radar (SAR) imaging when compared to traditional, fixed-wing, platforms. In particular, a swarm of UAS can ...
