To simulate the scattering of photons in sea fog particles， in this study， we use a Stokes vector to describe the polarization state of the photons， Mie scattering theory to calculate the Muller matrix and reflect the scattering characteristics of sea fog particles， and the Monte Carlo method to solve the vector radiation transmission problem in the sea fog environment. This paper discusses the changes in transmittance and reflectance with the transmission distance for sea fog particles of different radii， and the changes in the degree of polarization with sea fog visibility under different incident light polarization states and different incident light wavelengths. The results of the simulation experiment presented in this paper provide useful reference for research on the polarization transmission characteristics of light in sea fog particles.
