Wang Cui-hua · Journal of China University of Mining and Technology · 2007
In order to effectively solve the problem of monitoring timespace changes of soil moisture in large-scale regions,according to the conclusion of soil moisture retrievingby passive microwave remote sensing,a methodology of the soil surface emissivity was proposed by model BSM based on AMSR-E microwave remote sensing data,proof of the relationship between surface soil moisture and surface emissivity.A suitable artificial neural network models was established,and the emissivity for bare soil surface is calculated based on the theoretical backscattering model BSM.The results show that it's feasible to invert soil moisture by artificial neural network(ANN) based on BSM model and the technology is of promoting significance.
