Abstract
Three-dimension-field atmospheric turbulence based on Von Karman model was generated with Monte Carlo simulation, in view of correlation function matrix. According to the derivation of the Von Karman model formulae, the correlation curves of the simulated field can highly approach the theory results. The precision and efficiency of atmospheric turbulence simulation were improved by using double stochastic interchange minimization algorithm to improve Gauss white noise sequence, and also by the optimization of Monte Carlo method. The simulated atmospheric turbulence field, is identical with the Von Karman model by numerical test, and has perfect statistical characteristic and simulation precision. The simulation method could be used in real-time flight simulation.
