Based at Cranfield Defence and Security, the ground based Synthetic Aperture Radar (SAR) testing facility highlights include:

  • 3D through-wall SAR and automated collection of 3D SAR imagery;
  • Extreme high resolution SAR and Coherent Change Detection (CCD) images;
  • Coherent Change Detection imagery over non-flat terrain;
  • Hyperspectral SAR for material characterisation.

The GBSAR laboratory system can be run both indoor and outdoor.

Indoor system

The indoor system provides a highly controlled, precision, repeatable, radar-quiet measurement environment.

  • Housed within a flexible 17m (l) x 9m (w) x 5m (h) laboratory work space;
  • SAR and Tomographic profiling modes as well as reflectivity measurements;
  • Bi-static and multi-static configurations;
  • Automation allows collection of large continuous image sets for the study of slowly evolving scattering process - with no operator presence;
  • 4m x 1m x 1m sand trough used in the study of sub-surface imaging phenomena.
Imaging modes

: SAR. Tomographic profiling

Frequency: 500MHz to 26.5GHz (continuous P-through to Ku-band). To 50GHz by arrangement
Polarisation: Full quad
Nominal Accuracies: 1dB, 5degrees

Outdoor system

A bespoke, portable outdoor imaging system. Outdoor measurements allow the demonstration of techniques in more realistic conditions.

  • Trailer mounted hoist, transported to site by 4x4 vehicle;
  • For deployment: horizontal scanning boom attached to crane and lifted to chosen height;
  • Imagery captured by scanning antenna sledge along boom;
  • SAR and Tomographic profiling;
  • Controlled from a laptop at ground level;
  • Antenna sledge can be offset front-back for interferometric baseline;
  • Bespoke set-ups for bi-static imagery.
