Measuring the Microwave Backscattering Coefficient of Paddy Rice Using FM-CW Ground-Based Scatterometer

An experiment to measure microwave backscattering coefficients of paddy rice was carried out with FM-CW ground-based scattermeter at L-band, S-band, C-band, X- band. This paper introduces scatterometers that were adopted in the experiments and the measuring technique in detail, analyzes the data which were obtained under the different wave band and different polarized condition, and discusses the factors that affect emphatically the backscattering coefficient of scatterometer parameters: incidence angle, polarization, wave length.
