Research on the full stokes parameters from ocean targets using the laboratory simulated polarimetry system

摘要

In view of the ocean target quantitative characterization of full-stokes parameters, the laboratory simulated polarimetry system (LPOL) of ocean targets is designed. Carry out the experiments by this system, LPOL can change different relative observation angle under hemisphere space, which can obtain different polarization characteristic values of ocean targets and the background of the water, such as the degree of polarization, the degree of linear polarization and the degree of circular polarization, there is no research concern the influence of the full stokes parameters under hemisphere. In this paper, we systematically quantitative analysis stokes parameters of the experiment data which obtained under different zenith angle. The results indicated that the polarization detection, which use full stokes parameters can effectively distinguish between targets and background. Moreover, ocean targets have certain statistical regularity of polarization characteristics under hemisphere observation geometry space, such as bidirectional polarized reflectance factor. In this paper, the research results can provide a solid technical guidance for detect and recognize the ocean targets.
