Discrete scatter model for microwave response to agricultural fields

A coherent vegetation backscattering model which was developed by modifying the Michigan grassland coherent mode for the application of agricultural fields with uniform distribution was used in this research. The coherence effect between various scattering mechanisms is considered in this model. An experiment was carried out over a flat agriculture area located at Gongzhuling, in the Jilin province of China. Five rice and four corn fields were selected as the test targets and the plant and soil parameters were collected over a growing season for the models inputs. The model was used to simulate the backscattering coefficients of corn and rice fields respectively. It has been shown in this study that the results of corn field are better for the rice field.
