Abstract

The great east Japan damaged the east coast of Japan severely. NICT conducted urgent observations of the damaged areas by an airborne X-band SAR system (Pi-SAR2: polarimetric and interferometric SAR 2). In this paper we describe the detection of the damaged area by the earthquake and tsunami with polarimetric SAR data of Pi-SAR2. The space resolution of Pi-SAR2 is 0.3 m (slant-range) [1][2]. These SAR images of Pi-SAR2 are useful to detect the destruction of buildings and bridges and to identify flooded areas from the viewpoint of high resolution. We continue to observe the damaged area by Pi-SAR2 to monitor the reconstruction.
