Precise microwave scattering model of vegetation is the basic and key for understanding vegetation microwave remote sensing observations,development of remote sensing inversion algorithm,and improving the accuracy of vegetation parameters and soil moisture inversion.In recent decades,researchers established a series of microwave scattering model of vegetation based on electromagnetic scattering theory and radiative transfer equation for different vegetation types,which were widely used in microwave observations modeling and inversion.This paper systematically reviews the progress of the microwave vegetation scattering model in the aspects of theoretical model,semi-empirical model and empirical model.The main advantages and limitations of the three types of models are also proposed.Finally,the future trends of microwave scattering model of vegetation are discussed.
