摘      要：This paper retrieves the bidirectional polarization distribution functions (BPDFs) of the distinct urban cover in the Pearl River Delta (PRD) region employing the high spatial resolution of multi-angle polarized measurements made by the Directional Polarimetric Camera (DPC).The BPDF operational products of MICROPOL and POLDER measurements were used to validate the BPDF products of the DPC,with the results demonstrating that the BPDF product of the DPC measurements accurately expresses the surface polarized *** polarized reflectance of distinct surface types in the PRD region was studied using the DPC *** results demonstrate that the polarized reflectances of different surface types differ and decrease as the normalized difference vegetation index *** polarized reflectance of a distinct surface type in the PRD region decreases with increasing scattering *** basic theory of investigating surface properties using multi-angle polarized measurements is proposed.
