  • Aero-whisker for the measurement of aircraft flight speed and angle of attack in compressible flow conditions 
    Debiasi, Marco; Atkinson, Kevin; Saddington, Alistair J.; Finnis, Mark (AIAA, 2023-06-08)
    A whisker-like device has been designed and tested that simultaneously measures the speed and the direction of a flow in which it protrudes. The device consists of a thin cylindrical probe longer than the thickness of the ...
  • Laboratory bistatic synthetic aperture radar coherent change detection investigation 
    Hagelberg, Alexander; Andre, Daniel; Finnis, Mark (IET - The Institution of Engineering and Technology, 2023-08-10)
    Synthetic Aperture Radar (SAR) Coherent Change Detection (CCD) allows for the detection of very small scene changes. This is particularly useful for reconnaissance and surveillance as small changes such as vehicle tracks ...
  • Laboratory multistatic 3D SAR with polarimetry and sparse aperture sampling 
    Welsh, Richard; Andre, Daniel; Finnis, Mark (Wiley, 2024-01-01)
    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 ...
  • 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 ...
  • Laboratory multistatic polarimetric sparse aperture 3D SAR investigation 
    Welsh, Richard; Andre, Daniel; Finnis, Mark (Institute of Acoustics, 2023-12-31)
    Synthetic Aperture Radar (SAR) is a coherent technique that produces high quality imagery, with a finer cross-range resolution than would be possible with a stationary antenna. Radar pulses from multiple points along a ...
  • Multistatic 3D SAR imaging with coarse elevation and azimuth sampling 
    Welsh, Richard; Andre, Daniel; Finnis, Mark (IEEE, 2022-11-10)
    It is advantageous to produce Synthetic Aperture Radar (SAR) renderings in three dimensions as these allow the separation of features in height, providing additional target information. A Nyquist sampled 2D SAR aperture ...
  • Multistatic hybrid SAR/ISAR data generation using a stationary target 
    Rattan, Anmol; Andre, Daniel; Finnis, Mark (IET - The Institution of Engineering and Technology, 2023-02-07)
    There is great interest in multistatic synthetic aperture radar (SAR) systems as they are capable of providing high resolution images. These systems could prove promising candidates for provision of surveillance for both ...
  • Non-overlapping trajectory Multistatic SAR Coherent Change Detection 
    Hagelberg, Alexander; Andre, Daniel; Finnis, Mark (IET, 2022-04-21)
    Synthetic Aperture Radar (SAR) Coherent Change Detection (CCD) allows the detection of very small scene changes but is typically reliant on a high degree of similarity in the radar trajectories, with a small baseline. In ...
  • Polarimetric bistatic SAR image coherence 
    Hagelberg, Alexander; Andre, Daniel; Finnis, Mark (VDE Publishing, 2022-11-10)
    Synthetic Aperture Radar (SAR) Coherent Change Detection (CCD) allows the detection of very small scene changes, such as from ground subsidence or vehicle tracks, with applications both civilian and military. This high ...
  • Through-wall multistatic polarimetric 3D SAR 
    Andre, Daniel; Sabiers, Richard; Finnis, Mark (NATO Science and Technology Organization, 2022-06-12)
    Through-Wall (TW) Synthetic Aperture Radar (SAR) imagery can be difficult to interpret due to several factors including signal attenuation in highly cluttered environments, target overlay, difficult to interpret low SAR ...
  • Through-wall multistatic polarimetric 3D SAR 
    Andre, Daniel; Sabiers, Richard; Finnis, Mark (VDE Publishing, 2022-11-10)

  • Volumetric interferometry for sparse 3D synthetic aperture radar with bistatic geometries 
    Welsh, Richard; Andre, Daniel; Finnis, Mark (Institution of Engineering and Technology (IET), 2023-06-25)
    Synthetic Aperture Radar (SAR) renderings in 3D provide additional target information when compared to 2D by separating out features overlaid in height. However, the required 2D SAR aperture, when Nyquist sampled, necessitates ...
