Turtle Mountain Monitoring

Monitoring Changes Using GB-InSAR

We use ground-based interferometric aperture radar (GB-InSAR) to monitor rock movements on Turtle Mountain. GB-InSAR uses radar waves to measure ground movements.

About GB-InSAR

A ground-based interferometric synthetic aperture radar (GB-InSAR) acquires images using radar antennae that travels back and forth on a fixed rail. The antenna constantly transmits radar waves towards the target area and records their return time (wave phase). These phase images are combined to measure elevation changes within a few millimetres over a very broad area. If the amount of rock or debris movement on Turtle Mountain exceeds our threshold while monitoring, we are notified of the movement.
