Abstract
Very impressive phenomena due to the multiple backscattering were experimentally observed in the lidar backscattering from atmospheric water droplet clouds1) and the backscatterings from the random surface with relatively large slope in the correlation area2) and the spherical particles suspended in the water3). In the near field, (1) the bow-tie intensity pattern is produced in the co-polarized component1), (2) the cloverleaf intensity pattern is produced in the cross-polarized component2,3), (3) the intensity pattern enlarges radically and its contrast increases with a decrease of the particle size3). These may be attributed to the memory effect of the polarization in multiple scatterings. In this report, the numerical investigations are conducted by using the Monte Carlo simulations on the basis of a phase function for the Rayleigh-Debye scattering theory since the resultant polarization effects depend substantially on the polarization properties of the individual scattering event from the single particle with a finite size.
