Simulation model of laser transmission and detection through cumulus

We have developed a simulation model of laser transmission and Detection through cumulus. Based on successive-order-of-scattering approach, the model describes the transmission process of the laser beam under the impact of various media which are mainly cumulus in atmosphere. In this model, the factors affecting the laser transmission include aerosol, atmospheric molecules and water vapor molecules. The distribution of liquid water droplets in cumulus is described by two-dimensional model and Mie theory is used to calculate the optical parameters. In the life cycle of cumulus, the results can correctly describe the trends of laser power respect to target height and water droplets distribution of cumulus. The model can meet the requirements of real-time simulation. The model simulation process depends on the support of several parameters including equipment geometric parameters, atmospheric optical parameters and others.
