PRELIMINARY STUDY ON THE RADAR VEGETATION INDEX (RVI) APPLICATION TO ACTUAL PADDY FIELDS BY ALOS/PALSAR FULL-POLARIMETRY SAR DATA
SAR Radar Vegetation Index
2015/5/6
Kim and van Zyl (2001) proposed a kind of radar vegetation index (RVI). RVI = 4*min(λ1, λ2, λ3) / (λ1 + λ2 + λ3) They modified the equation as follows. (2009) RVI = 8 * σ0 hv / (σ0 hh + σ0 vv +...
