Home > Capability Details SAR Interferometry Analysis Ground deformation monitoring by Persistent Scaterer Points (PSP) Synthetic aperture radar (SAR) interferometry is a powerful technique to determine the topography of the observed scene and possible slow surface movements due to subsidence, landslides, seismic and volcanic phenomena. The PSP-IFSAR technology provides millimetric measurement of ground displacements from series of satellite SAR data. The PSP measurements are obtained corresponding to objects exhibiting radar backscattering properties stable over time, called persistent scatterers (PS). Infrastructure management requires the constant monitoring of networks, both linear or defined by a complex matrix of roads, cables, bridges, railways and yards spread out over many acres of land even in remote areas. States and Industries need a single way to monitor all this complex network in order to guarantee the maximum levels of both service and safety. Landslides, floods, trees or illegal buildings could all impact the safety of those using the networks, and businesses are constantly working to mitigate against these risks using interferometry or highly detailed orthoimages to detect individual changes and obtain valuable information throughout the network's lifecycle.
