SAR-Interferomerie für das Monitoring von Vulkanen: 3D-PSI-Analyse und Kompensation des atmosphärischen Brechungsindex

摘要

Advanced SAR interferometric techniques are developed in order to retrieve surface deformation signals at active volcanoes. The persistent scatterer interferometry method is investigated and demonstrated. An effective method using numerical weather data for the mitigation of the atmospheric delay due to vertical stratification is developed: the direct integration method. A multi-track fusion algorithm based on the iterative closest point algorithm is developed and investigated.
