CIUDEN - Deformation monitoring during the period of CO2 injection by means of SAR techniques

Deformation monitoring will be carried out through observations taken at the surface level, i.e. avoiding test drilling costly operations. In addition, most of the data can be acquired by means of remote sensing techniques that need a limited access to the study area. Deformation monitoring techniques include a wide range of methods with very different characteristics, performances and cost. Considering the type of study, the IG proposes to consider, in the first approach, the use of interferometric techniques based on SAR (Synthetic Aperture Radar) data.It is expected to work at two different scales using two complementary interferometric techniques, depending on the general characteristics of the study area and, especially, on the required spatial and temporal resolutions,. The first technique, DInSAR (Differential Interferometric SAR), is based on satellite SAR data. The second one, GB-SAR (Ground-Based SAR), is based on terrestrial instrumentation (close-range remote sensing).
