To enhance the physical realism of sea surface simulation,this study explores the influences of distinct simulation parameters on the surface's simulation accuracy and establishes criteria for selecting appropriate simula-tion parameters when simulating the sea surfaces.According to wave spectra and random process statistics theory,the autocorrelation function is employed to investigate the variation in the correlation length of sea surfaces with the change of wind velocity.Through the establishment of a Monte-Carlo simulation model and combining it with error analysis in generating random rough surfaces,the paper proposes criteria for selecting simulation parameters for sea surface scenes under varying wind velocities.The results indicate that restricting the sampling interval within the range of 0.1～0.5 times the correlation length along the downwind direction can significantly enhance the accuracy of sea surface simulation.In contrast,the existence of sea surface simulation parameters exceeding this range may cause distortions in the simulation,thereby impacting the visual realism.The proposed simulation parameter selec-tion criteria can provide technical support for the development of marine simulators.
