Multiple Random Phase-Screen Simulation of Scintillation Effect of Bessel-Gaussian Beam in Ocean Turbulence
Based on the generalized huygens-fresnel principle,this paper use the power spectrum inversion method to produce ocean turbulent phase screen simulation model.And study the Bessel-Gaussian beam(BGB)scintillation characteristics in ocean turbulence.The results show that the higher the turbulence of the ocean is,the more serious the phase distortion is,the more obvious the scintillation is,and gradually degenerates into the normal Gaussian beam(GB).With the increase of transmission distance,the increase of the order of the BGB,the increase of waveform parameters,and the decrease of the rate of dissipation of kinetic energy per unit mass of water are the stronger the scintillation effect in the ocean turbulence.And the BGB has a critical beam width value,which is far away from the value and its scintillation effect is stronger in ocean turbulence.The study provides a theoretical basis for the transmission and communication of vortex beam in ocean turbulence.
