    Deformation monitoring using InSAR and artificial reflectors

  • Original language 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 monitor
