I

Interferometric Radar

A radar technique that measures distance changes by comparing the phase of radar signals over time, enabling millimeter-level accuracy in deformation monitoring.

Interferometric radar, also known as InSAR (Interferometric Synthetic Aperture Radar), is the core technology behind modern deformation monitoring systems. By analyzing the phase difference between successive radar measurements, it can detect movements as small as 0.1mm.

S

Slope Deformation

The gradual or sudden movement of soil and rock masses on a slope, which can lead to landslides if not monitored and managed properly.

Slope deformation is a critical safety concern for highways and railways built on or near slopes. Early detection through continuous monitoring enables preventive measures before catastrophic failure occurs.
