| Description
| - The SAR interferometry (InSAR) method can be used to create digital elevation model (DEM), or to monitor terrain deformation or some features of the atmosphere. The method uses several satellite radar images, to form interferograms from pairs of them. The interferogram always contains several components: the flat Earth, topography, deformations, atmospheric influence and noise. The aim is typically to extract one of the components and therefore, it is possible to estimate and subtract (or neglect) the others. A big problem of this method is so-called decorrelation, i.e. if the noise is significantly higher than other components. Mostly, it happens in vegetated areas - forests, agricultural fields, meadows, mostly during late spring, summer and early autumn. Such vegetated areas can be monitored only during winter (if no snow is laying), but with lower accuracy. Much better results can be gained in urban areas, which are stable in time (in the order of centimetres). We deal with monitoring of deformations, which occur due to undermining or subsidence (on waste dumps), or due to landslides, mostly in the Nothern-Bohemian coal basin. We cooperate with the Coal Services, a.s., company, and within this project there were 11 artificial corner reflectors installed in the mines surroundings (near the Most city). The places to install the reflectors were selected by the company as the most important places to monitor. This is the only way to monitor areas containing a very small amount of artificial objects. Now, the corner reflectors are monitored by German satellite TerraSAR-X, which enables acquisition of images with resolution of approx. 3x3 m. The corner reflectors can be found in the scene as very light points (with respect to their surroundings), about 2x2 pixels large. It is impossible to find one of the reflectors, because it is placed in the area of radar foreshortening/layover.
