Focusing on the demand about high-precision obtaining all-sky polarization pattern information,a measuring system of atmosphere polarization pattern based on polarization analyzer,the level turntable and the height regulating station was constructed,which achieves the all-sky polarization pattern by scanning.Using the Matlab to processing and analysis the measured data,combining with the Rayleigh scattering model to reconstruct the 2and 3-dimensional atmospheric polarization pattern.The result indicates that the measured polarizing information is 92%,which measure error of polarizing angle is less than 0.5,and the measured polarizing information is 87%,which measure error of polarizing degree is less than 0.5.It is basically consistent with the theoretical Rayleigh scattering model and the measured information of the atmospheric polarization is accurate.Then we can lay the foundation for the subsequent application and algorithm of polarized navigation.
