Abstract :
The damaged Area by tsunami at the great east Japan earthquake in 2011 was observed by the airborne X-band SAR system (Pi-SAR2). In this paper we describe the polarimetric character of the damaged area and detect the damaged area from the SAR image on March. Moreover we use the change of SAR images between March and August to evaluate the damaged area detected by the polarimetric character.
