The Japanese ALOS-2 satellite was launched on May 24th, 2014. It has the L-band SAR, PALSAR-2. Kim,Y. and van Zyl, J.J.\udproposed a kind of Radar Vegetation Index (RVI) as RVI = 8 * σ0hv / (σ0hh + σ0vv + 2* σ0hv) by L-band full-polarimetric radar\uddata. Kim, Y. and Jackson, T.J., et al. applied the equation into rice and soybean by multi-frequency polarimetric scatterometer\udabove 4.16 meters from the ground. Their report showed the L-band was the most promising wave length for estimating LAI and\udNDVI from RVI. The author tried to apply the analysis to the actual paddy field areas, both Inashiki region and Miyagi region in\udthe eastern main island, “Honshu”, areas of Japan by ALOS-2/PALSAR-2 full-polarimetry data in the summer season, the main\udcrop growing time, of 2015. Judging from conventional methods, it will be possible to discriminate paddy rice growing fields from\udreaped fields or the other crops growing fields by the PALSAR-2 data. But the RVI value is vaguely related to such land use or\udbiomass at the present preliminary experiment. The continuous research by the additional PALSAR-2 full-polarimetry data should\udbe desired
