Summary:

In the article there was described the example of using ground radar inter-ferometry technique for landslide's monitoring. Monitored object is located in Milówka (Poland). Author described shortly the causes of landslide occurring and the geological elements of typical landslide. Reference was made to monitoring surveying techniques according to characterization of used technique. Ground ra-dar interferometry technique allows us to determine displacement of never before seen precision, in a real time and without the need to enter the monitored object. Possibilities of using ground radar interferometry has been tested by performing several measurement series in two days. For example, the displacement of measurements can be concluded that the use of ground radar interferometry allows to determine the displacement of a millimeter accuracy, while reducing the measurement time, limit the composition of the team qualified for the measurement of one person and get immediate occurring value of displacements. Acquisition and analysis of data in real time creates the potential for warning about the loss of soil stability, which is certainly important for the safety of residents and their homes were located in the landslide areas.
