Design of atmospheric turbulence phase screen set under the influence of combined oblique propagation and beam propagation

In this paper, the wavefront aberration was simulated by using the phase screen set under the influence of combined oblique propagation and beam propagation. First, the phase screen of the vertical transmission path was generated by the power spectrum inversion method and the subharmonic compensation method, and the oblique atmosphere propagation theory was used to correct the phase screen, then the phase screen suitable for the simulation of the influence of the oblique atmospheric turbulence was obtained. The difference of phase structure function between oblique phase screen and vertical path phase screen was compared by numerical analysis. The space distribution of wavefront distortion corresponding to each height interval was calculated, and the phase screen group model was established. Finally, the phase distribution of each position of the received light wave plane was obtained.
