Using the angular spectrum representation of plane waves, we investigate the scattering of multi-Gaussian Schell-model (MGSM) beams from a random medium within the accuracy of the first-order Born approximation. The far-zone properties, including the normalized spectral density and the spectral degree of coherence, are discussed. It is shown that the normalized spectral density and the spectral degree of coherence are influenced by the boundary of the beam profile (i.e., M), the transverse beam width, the correlation width of the source, and the properties of the scatterer.
利用平面波的角谱表示，我们在一阶玻恩近似的精度范围内研究了多高斯谢尔模型（MGSM）光束在随机介质中的散射。讨论了远场特性，包括归一化谱密度和谱相干度。结果表明，归一化谱密度和谱相干度受光束轮廓边界（即M）、横向光束宽度、源的相关宽度以及散射体特性的影响。
