Polarized reflectance data of dry soils and soils containing 18% of water are collected with bi-directional reflectance detection instrument. The specialties of this instrument lies in its ability to measure the polarized reflectance of targets at various zenith viewing angles, incidence light zenith angles and azimuth angles with band A (630-690nm) and band B (760-1100nm). So analysis according those characteristics listed above is done. It is found that soils reflectance characteristics have direct relation with soil type, soil property and sensor's viewing geometry. This study on polarized reflectance of soils can not only help to find a new way for soil remotely detection but also provide the theoretical basis for further researches on the remote sensing of polarized light.
