| Abstract: | In order to make a good use of Chinese polarized satellite sensor, the directional polarized camera (DPC) has been developed and tested in the flight experiments. DPC camera is designed to observe the polarized and directional reflected radiation of the earth-atmosphere system. Retrieval of physical parameters from DPC data depends on the accuracy of calibration. The polarized camera radiative calibration includes two aspects: intensity and polarization. Based on the predecessors' work, we explore the polarization calibration principles and methods. Using the DPC aerial remote sensing experiment data, we have realized the polarization calibration and analyzed the results. This work may contribute to fundamental basis for the data processing and in-flight calibration of the future Chinese polarized satellite sensor. |
