In this paper, the Monte Carlo simulation results of laser radar echo signals and multiple scattering intensity distributions are briefly reported. The laser radar system adopts a coaxial design. In the calculation, spherical mist particles with a certain thickness and uniform distribution are used to simulate the atmospheric environment. The influence of the particle size on the echo signal is studied. Different particle radii and different acceptance angle conditions Empirical formula for the distribution of multiple scattering signal intensities. The above two sets of empirical formulas have good correction coefficients and can be directly used for the research of multiple scattering effects in the design of laser radar systems, saving a lot of simulation time and improving the design efficiency
