Analysis of the Relation Between S-Band Backscatter and Ranks Distribution of Wheat

The paper described multi-temporal measurements of wheat using ground-based radar scatterometer (GBRS) system and investigated S-band scattering character of wheat parameters to ranks distribution during an entire growth cycle. S-band was chosen for its distinct behavior from popular L and C bands. The difference of backscatter for ranks distribution (row and column) were analyzed as the function of the wheat temporal variations parameters, such as wheat age, biomass, canopy height, LAI at six experimental acquisitions. The research showed the S-band scattering character of wheat parameters to rank distribution has different formulation mechanism and influence on total backscatter. Moreover, the relation between backscatter and ground data had also been analyzed. The research results could be helpful to provide a reference for modeling and cereal monitoring by remote sensing technology.
