Remote sensing, monitoring and EWS

Theme: Identification and measurement
The focus of the development of measurement technology will be on remote monitoring using geophysical methods, in particular inSAR and GinSAR.  Historical satellite data exists from 1991.  R&D work on traditional measurement technology itself (e.g. development of a sensor) will not be considered, however the implementation of sensor systems utilizing traditional technology to address geohazard issues are a natural component in this project. 

GinSAR and inSAR are complementary because inSAR (satellite based) data is not available everywhere, while GinSAR is a portable system that can be deployed at specific locations as needed. GinSAR can provide better resolution, and may be configured to capture horizontal displacements as well as vertical.  InSAR provides the capability to monitor large regions and inaccessible areas, but has lower resolutions and cannot capture predominantly horizontal displacements and may not be applicable in areas with very steep slopes.

• GinSAR - The goal of the work on Ground based Interferometric Synthetic Aperture Radar (GINSAR) technology is to develop equipment for measuring small displacements of rock slopes,  Spin off technology is also available, for example for monitoring of clay slopes and snow accumulation for avalanche warning. This is the focus of the PhD student
