DinSAR

MetaSensing offers a range of ground-based and airborne radar sensors for natural and man-made hazard prevention and monitoring. We use top-level radar technology and signal processing to provide risk assessment and early warnings.

DinSAR application

The MetaSensing’s MetaSAR can be integrated into small airplanes, helicopters or UAVs for a customized and cost-effective deformation monitoring over large areas.

By using processing techniques such as Differential Interferometry (DInSAR), Amplitude Change Detection (ACD) or Coherent Change Detection, it is possible to retrieve the displacement and velocity of slow terrain movements, from a few mm per year up to several cm per day.

Advantages

  • Flexible revisit time: the periodicity of data acquisition can be chosen according to the dynamics of the changes or of the terrain movements
  • The operational frequency can be selected to maximize the return on a specific terrain type
  • Track and flight height can be suited to avoid shadowed regions, and to optimize the Line-of-Sight with respect to the direction of the movement of interest

Applications

  • Platform: UAVs
  • Operational frequency: from P to X band
  • Flight altitude: from 50 m to 1000 m
  • Swath: Up to 5 km
  • Slant Range Resolution: from 0.75 m
  • Size [cm]: 30 (L) x 30 (W) x 25 (H), customizable
  • Weight: 11 Kg
  • Power consumption: < 200 W

Key features

  • Monitoring of terrain movements: Open-pit mining activities, subsidence, landslides, erosion
  • Monitoring of land use: deforestation, urban growth, illegal settlements
