The model of phase screen for numerical simulation of laser propagation in rain is suggested. Since the optical radiation scattering on rain drops is considered within the diffraction approximation for the scattering phase function, the spectrum of correlation function of water drop dielectric permeability fluctuations in the atmosphere has a Gaussian form. The simulation results are compared with known theoretical estimates. The averaging effect of the receiver on measured parameters of laser radiation is investigated.
