The uncertainty of the Mueller scattering matrix of nonspherical aerosol is a significant factor influencing the accuracy of polarization sensing. In the self-developed multi-resolution time-domain (MRTD) aerosol scattering model, the Mueller scattering matrix should be calculated from the electric field in far region. Therefore, the near-to-far field transformation process becomes an important step influencing its simulation accuracy. In order to determine the best near-to-far field transformation scheme for MRTD scattering model, the simulation accuracy of the Mueller scattering matrix corresponding to the surface integration scheme based on Huygens principle and the volume integration scheme based on Helmholtz equations for dielectric medium is compared and analyzed systematically in the case of spherical and nonspherical particles. The results show that, although both of the near-to-far field transformation schemes can achieve near-to-far field transformation effectively and accurately, the near-to-far field transformation scheme based on volume integration principle has better performance based on the calculation error distribution of the Mueller matrix.
