Abstract
Vegetation water content (VWC) is an important parameter of agriculture and forestry. In this letter, specific polarization ratios were evaluated for estimating VWC of corn and soybean. Backscattering coefficients (σhh, σvv, σvh and σhv), polarization ratios (σhh/σvv,σvv/σvh, and σhh/σhv), and the radar vegetation index derived from L-band (1.26 GHz) and S-band (3.15 GHz) radar data of the passive...
