Abstract

In this paper, a simulation experiment is done to study the influence of atmospheric turbulence on the laser beam in the process of oblique transmission. The horizontal random atmospheric turbulence phase screen group is generated by using the power spectrum inversion method plus sub-harmonic compensation method, and the position distribution of the phase screen on the inclined transmission path is corrected by combining the atmospheric refractive index structure parameters that vary with height. Atmospheric turbulence phase screen set suitable for simulating slant laser transmission. Through simulation, the far-field light intensity distribution of the inclined transmission phase screen group and the horizontal transmission phase screen group is compared. The results show that, compared with the horizontal atmospheric turbulence phase screen group that does not consider the atmospheric refractive index structure parameter changing with height, the far-field light spot of the laser beam after passing through the oblique transmission phase screen group is more obvious, and the light intensity attenuation is more serious. The modified slope phase screen group is more accurate in simulating the effect of atmospheric turbulence on the laser beam.
