Optimization of satellite insar techniques for monitoring of subsidence in the surroundings of Karvina mine: Lazy plant
This paper deals with issues related to convenient monitoring of subsidence due to longtime mining activities of Czech
Karviná Mine: Lazy plant, using satellite SAR interferometry (InSAR) techniques. It maintains approaches for optimizations
of differential InSAR, especially including available filtering possibilities. It was realized that current SAR satellites were not
able to appropriately evaluate deep subsidence as it occurs in Czech mining sites. Other issues are related to the presence of
dense vegetation. Data from previous and only available L-band SAR satellite ALOS demonstrates its high potential in this
area of interest. However, only a few acquisitions are available of the mining site disallowing usage for purposes of
continuous monitoring of subsidence in the area. Processing results of InSAR techniques of the Lazy plant are presented in
this paper.Web of Science101656
Interferometric Synthetic Aperture RADAR and Radargrammetry towards the Categorization of Building Changes
The purpose of this work is the investigation of SAR techniques relying on multi image acquisition for fully automatic and rapid change detection analysis at building level. In particular, the benefits and limitations of a complementary use of two specific SAR techniques, InSAR and radargrammetry, in an emergency context are examined in term of quickness, globality and accuracy. The analysis is performed using spaceborne SAR data
