| Description
| - North-Bohemian coal basin is a largely unstable area with very old mining sites, which are potentially dangerous for people living there. Mining has been performed for several centuries; deep mines were active in the past (the surface above is not expected to subside any more), and currently open-pit mines are used for exploitation. Most of them are later reclaimed to forests, lakes, agriculture fields etc. Landslides and subsidence occur in these areas and they need to be monitored. In addition to classical levelling methods new methods are being used for detection of possibly dangerous areas. One of them is radar interferometry. It allows for Earth-crust deformation mapping with the use of satellite images, without the necessity of expensive on-site measurements. Its accuracy may even reach several mm/yr in the theoretical case. This method is usable in areas with low amount of vegetation and for objects, which are not expected to change their spectral characteristics during monitoring. This applies to artificial objects (buildings, roads, railways), which are of most interest to public (centres of villages, cultural monuments, communications and industrial areas). A significant limitation of standard InSAR processing is the impact of atmosphere, which shows strong spatial correlation and is uncorrelated in time, whereas target motion is usually correlated in time. Therefore the method of Permanent Scatterers is used in order to deal with this atmospheric effect. To improve the method, corner reflectors are installed in the neighbourhood of the area of interest. That usually is in village centres, next to cultural monuments and water reservoirs and some in industrial areas.
