Monitoring bridge deformation in the Czech Republic with Sentinel-1 data

Popis výsledku v původním jazyce

In the Czech republic, as well as in other areas, the bridges are of various age and various condition. It seems that more problems can be found on recently- built bridges, but this is due to the fact that the old ones are usually not monitored in such a detail or not at all. The aim of monitoring bridges is to find possible deformations before the deformations get large/significant to endanger the people and/or traffic. However, there are more deformation causes of the bridges, and most of them are reversible, such as thermal dilation, bending with load etc. The problem is to recognize these components from the irreversible deformations, and one needs a large dataset, covering at least 18 month data (to separate the thermal dilation component from the linear deformation component). The direction of the irreversible movements can be arbitrary, and due to the easily accessible Sentinel-1 data, we try to monitor the bridge from various directions.For improving the accuracy we plan to make experiment with corner reflectors to enhance the intensity, and therefore to lower the standard deviation of the movement, however this experiment will be evaluated in future.Our project monitors few bridges in the Czech republic, of various length and age.
