WebbMultiple Random Phase-Screen Simulation of Scintillation Effect of Bessel-Gaussian Beam in Ocean Turbulence Abstract: Based on the generalized huygens-fresnel principle, this paper use the power spectrum inversion method to produce ocean turbulent phase screen simulation model. WebbTwo different approaches for computing phase screens with this spectrum are considered. In the first approach, the phase screens are computed directly from the spectrum by inverse transformation. Gaussian random numbers are molded to the spectrum. A discrete 2D Fourier transform provides sample random phase screens.
