The S-band and C-band FM-CW land-based radar scatterometers were used to measure the backscattering coefficient of a variety of typical earth substances in northwest of China, including: bare soil, frozen soil, bulrush and maize etc. under the different time and different wave band and different polarized condition. First of all, the measurement principle and performance parameters of scatterometer...
In this study, a multi-band FM-CW land- based scatterometer is used to measure the backscattering coefficient of bare soil surface. And then combined with the neural network which can be simulated in any nonlinear problem in theory, and integrated equation model (IEM) which has a wide range of surface roughness, has realized all of the surface parameters inversion through the theoretical simulation...
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...
