| Outline of Final Research Achievements |
In order to evaluate the possibility whether satellite-borne Synthetic Aperture Radar(SAR) can detect structural changes of large scale artificial structures such as big bridge or buildings, recent SAR application for urban areas are surveyed from literature and research conferences.
We analyzed full-polarimetric SAR measurement data over western part of Tokyo where large bridge and buildings are located. It is well known that the relative height of the persistent or permanent structures can be estimated precisely by interferometric technology. We try to seek more simple method to extract any changes of the structures by fully making use of full-polarimetric measurements. From analysis using phase information in each measurement polarization pairs, it is suggested the possibility to find changes of the structures if many scenes are available and the effect of atmosphere including ionosphere effects are compensated.
