Selection of Computing Parameters in Numerical Simulation of Laser Beam Propagation in Turbulent Atmosphere
激光湍流大气传输数值模拟中计算参量的选取

Based on sample principles,properties of turbulent media,turbulent effects and light propagating effects,criterions for grid interval,inter-screen distance and number of grid were analyzed.By numerical analysis,it is shown that not all of these criterions can be satisfied simultaneously in most simulations.If parameters were selected strictly according to these criterions,the demand of calculation would be out of reach of a computer.Then,taking into account the burden that a computer can bear and simulated precision,a reliable and applicable method of the selection of crucial computing parameters was presented.
