Abstract:Current polarization detection is mainly based on the polarization state of at-sensor radiance, w hich can enhance objects of interest or restrain background disturbance qualitatively. There is only empirical linear method for polarized reflectance retrieval of ground objects, w hich is inadequate in terms of adaptability and real-time capability under varied observation conditions. A polarized reflectance retrieval method based on polarized atmospheric radiative transfer model is hereby proposed. A lookup table ( LUT) is established by using the radiative transfer model to illustrate the relationship among polarized reflectance, observation condition and at-sensor polarization state. Polarized reflectance can then be retrieved using the LUT combined w ith numerical calculation. Results show that the retrieval accuracy of polarized reflectance of typical ground objects can be up to 90%.
