Ground based radar interferometry is one of the currently used, remote measurement technologies allowing to determine the displacements of the monitored area. This technology use a radar operating in the microwave band, which emits a beam in the direction of the monitored area, and then after reflection processes and registers it in the form of radar image.
In order to determine the value of the displacement it is necessary to perform at least two measurements on the basis of which the interferogram is generated. Changing the weather conditions between two measurements effect on the obtained values of displacements. In order to eliminate the impact of atmospheric correction the control points in the form of corner reflectors are applied. The corner reflectors give a strong reflection of radar waves and are clearly visible on the interferogram. In this example the measurements results of unstable slope movements has been presented. On its upper part, in the area considered to be stable, three control points were mounted, and from the opposite slope measurements were obtained using a ground radar interferometer obtaining totally 36 radargrams. In post processing interferograms based on one, two or three control points were generated, and for the selected area points the values of obtained displacements were summarized, which constituted the basis for assessing the impact of the weather on the measurement results. |
