X Ray Eyes: Seeing Through Walls Using Radar

Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Digital Image presented at the 2018 Defence and Security Doctoral Symposium.
This image represents current research into ground-based applications of radar imaging in a through-wall context. Utilising different measurement geometries and signal processing, the aim is to gather and disseminate low-frequency synthetic aperture radar data to identify building structure and content.
This image shows volumetric synthetic aperture radar data gathered in a multistatic modality, i.e. where there are two independent receiving antennas, both on the far side of the wall. This is superimposed onto a photograph of the same area, showing good agreement between the visual and radar images. For clarity, the point cloud has been segmented into different regions, each given a separate colour. Red represents the two metal barrels, blue shows the desk area whilst green represents the wall signature.
