Land displacement monitoring (InSAR Ground Deformation Monitoring) is carried out through the implementation of interferometric processing of multi-pass radar images of the same area, acquired with the same technical parameters and imaging geometry.

Radar interferometry allows for the detection of surface displacement and objects located on it with centimeter-level accuracy (for the Earth's surface) and millimeter-level accuracy (for buildings and structures), using spaceborne radar images as input data.

Geodetic monitoring aims to detect deformational changes, determine the causes of their occurrence, and provide forecasts for their future development and changes.

To detect and assess ground displacements above areas of underground mining, map the deformation of quarry walls and benches, or identify deformations of structures, expensive GPS monitoring is not necessary. Radar interferometry allows achieving millimeter-accuracy measurements over large areas, comparable to the precision of GPS monitoring, without the need for costly field infrastructure.

Radar interferometry is indispensable for:

• Timely detection of ground displacements above areas of underground mining;
• Mapping deformations of quarry walls and benches;
• Monitoring natural and man-made displacements and deformations of buildings and structures;
• Monitoring critical industrial facilities, pipelines, roads, railways, and other objects.
