| Outline of Final Research Achievements |
We have developed new methods and algorithms to detect, localize and classify buried objects from airborne, space borne and ground-based polarimetric SAR data. We have developed a new polarimetric GB-SAR system which allowed, together with the use of state of the art airborne and space borne SAR data from Japanese sensors operating at different radar frequencies, to successfully detect more than 40 subsurface objects. A novel approach to classify buried objects based on their polarimetric signatures was proposed. For the first time ever, we successfully obtained SAR data from bistatic ground-based/airborne experiments. The results demonstrate the potential for the detection and localization of buried objects from fast, aerial radar measurements which can contribute to drastically improve disaster response after events like earthquakes, tsunamis, landslides, volcanic eruptions or avalanches. Two journal papers were published and one more is being prepared for submission.
