Abstract
In the experiment, spectral reflectance distribution function (spectral polarimetric BRDF) of soil was measured in the visible band (400-720 nm) and the relationship between variation of spectral polarimetric BRDF(pBRDF) with observing angle and wavelength was analyzed. As the Hapke model can well describe the interaction between incident radiation and surface features, the Hapke reflectance model was used to complete modeling of BRDF intensity component for soil in the visible band. By comparing predicted value with measured value, it is known that the intensity model used in this paper can describe the characteristics of the soil with great accuracy, so it is possible to analyze the trend of soil model parameters according to the established model. Under certain conditions, it may reflect some characteristics of the soil itself. The relationships between the degree of polarization and detection angle, wavelength and intensity component for soil were also analyzed, and it has theoretical significance for the study of polarization properties of the soil.
