摘要

A nonuniformly polarized beam array (NUBPA) is modeled by coherent superposition of a pair of orthogonally polarized spatial modes. The propagation of a NUPBA in turbulent atmosphere is investigated based on the extended Huygens-Fresnel method. An analytical expression for the intensity profile of a NUBPA in turbulent atmosphere is presented. The influence of polarization degree, intensity of turbulence, array number, and distance between adjacent elements on the intensity profile in the receiving plane is evaluated numerically and analyzed in detail.
