Abstract
Moisture is one of the most important parameters affecting soil polarization spectra, and is critical to soil remote sensing band selection and image interpretation. It also provides information required for soil investigation and analysis of physical and chemical properties. In this paper, we tested and analyzed the polarization spectra of soils with different moisture contents in the wavelength range of 350 nm to 2500 nm to study the relationship between soil spectral polarization data and soil moisture, to determine the spectral response and changes in soil moisture, and to establish models of the relationship between spectral data and soil moisture. We also designed an orthogonal test for the various factors that affect soil spectral polarization characteristics, in which we studied soil moisture, polarization angle, detected angle, and azimuth of the various factors and their interactions. The results showed that the most significant factors were soil moisture and the interaction of soil moisture and polarization angle, followed by the interaction between the detected angle and moisture, while the polarization angle had little impact on the soil polarization spectra.
