Possibilities of precise determining of deformation and vertical deflection of structures using ground radar interferometry

The contactless determination of deformations and deflections of structures with accuracy up to 0.01 mm in real time can also be used in practice the technology of ground based radar interferometry. It is also possible in real time to capture oscillations of the object with a frequency up to 100 Hz. Deformations can be determine simultaneously in multiple places of the object, for example a bridge structure at points distributed on the bridge deck at intervals of one or more meters. This allows to obtain both overall and detailed information about the behavior of the structure during the dynamic loading. In addition to the necessary principles are given practical examples
