S-band backscattering analysis of wheat using tower-based scatterometer

This paper investigates the S-band backscattering variation of wheat in its four growing seasons, with the purpose of providing a reliable method for wheat identification and monitoring using satellite S-band synthetic aperture radar (SAR) data. The study is based on the tower-based scatteromerer experiment conducted on the wheat fields at the remote sensing test site of Institute of remote sensing applications Chinese academy of sciences. During the entire growing season, we carried out four experiments and got a great amount of backscatter data including the HH and VV polarization. Synchronously, a wide range of plant parameters, such as biomass, soil moisture and canopy height were measured. This paper describes these experiments and analyzes wheat temporal backscattering variation at S-band with corresponding ground parameters.
