Ground-based interferometric radar systems

Terrestrial Radar Interferometry (TRI) is a powerful remote sensing technique for detecting ground movement with millimetre-scale accuracy. By using a stationary radar, it enables continuous, near real-time monitoring of unstable slopes, glaciers, and other critical landforms.

Purpose & Applications
TRI is essential for understanding and mitigating geohazards. Its applications include:

  • Geohazard Monitoring: Tracking displacement of landslides and unstable rock faces for early warning and risk assessment.
  • Climate Impact Studies: Observing how landforms like glaciers respond to environmental drivers such as temperature and precipitation.
  • Infrastructure Safety: Supporting the monitoring of mines, dams, and other critical infrastructure.

Expanding National Capacity
The EPOS-NG project will strengthen Norway’s TRI capabilities by:

  • Acquiring a new TRI system for NGI in Oslo.
  • Upgrading the existing system at NORCE in Tromsø.

Both partners bring extensive expertise in developing TRI applications for early warning, slope stability, and ice dynamics.

A Coordinated National Resource
This coordinated pool creates a unified national infrastructure, significantly enhancing our ability to assess and monitor hazardous ground movement. It serves a broad community, including universities, research institutes, municipalities, engineering firms, and infrastructure owners engaged in geohazard research and management.
