This paper presents time series results of X-band fully Polarimetrie radar observation of wetland “Sakata” in Niigata, Japan, during 2013 to 2015. The polarimetric scattering power decomposition was applied to the data sets. The region was successfully imaged by a very high-resolution (30 cm) polarimetric airborne SAR system, which revealed the detailed characteristic response of the emergent plants...
SAR remote sensing has been expected as an efficient rice crop monitoring tool due to its flexible operability with wide swath. Though many researchers have intensively analysed the backscatter, there still exist non-negligible mysteries to extract physical parameters. To solve the problems, it is essential to conduct theoretical characterization of experimentally obtained radar backscatter from rice...
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...
