The effect of anisotropic oceanic turbulence on propagation characteristics of twist Gaussian Schell-model array beams is investigated. The analytical expression for the cross-spectral density function of such beam propagating through turbulent ocean is derived and used to explore the evolution behavior of the spectral intensity and the degree of coherence. An example illustrates the fact that, the most important oceanic effect is destroying the far zone lattice-like beam profile, and the beam shape eventually converges into Gaussian profile. Besides, after passing through the turbulence at sufficiently large distances from the source, the twist phase modulation of the second-order statistical properties is shown to be suppressed by the turbulence fluctuation, the spectral intensity evolves in the same way with different twist strength, and so is the case for the degree of coherence. The impacts, which arise from the source coherence and the turbulence parameters on beam characteristics are analyzed in detail.

研究了各向异性海洋湍流对扭转高斯谢尔模型阵列波束传播特性的影响。推导了这种光束在湍流中传播时的跨谱密度函数的解析表达式，并用于探索光谱强度和相干度的演化行为。一个例子说明了一个事实，即最重要的海洋效应是破坏了远区格状光束轮廓，并且光束形状最终收敛为高斯轮廓。此外，湍流经过离源足够远的湍流后，湍流波动抑制了二阶统计特性的扭曲相位调制，光谱强度以相同的方式演变，但扭曲强度不同，连贯程度也是如此。详细分析了源相干性和湍流参数对光束特性的影响。
