ABSTRACT:
A slope monitoring system having a radar and a video camera recording images sequences of the slope. A data processing unit performs coordinate registration to align the radar images and the video images. Interferometry is used to detect movement in the slope by generating interference maps between the images. These are suitably phase maps showing the phase change between a radar image and a reference image. An alarm occurs if a significant movement is detected.
