为了研究大气湍流的闪烁效应对合成孔径激光雷达成像的影响，基于Kolmogorov湍流谱模型，根据Mellin变换技术及随高度变化的大气湍流结构常数模型推导了大气湍流中激光波束斜程传输时接收机处波束的对数振幅方差；数值分析了不同目标高度、不同波长情况下对数振幅方差随传输距离的变化关系；利用此结果根据大气湍流中激光反射回波闪烁效应的概率密度函数对大气湍流中未经滤波的合成孔径激光雷达成像进行仿真，结果表明随着波束对数振幅方差的增加即湍流强度的增加，图像变得越来越模糊。特别当湍流接近饱和时，目标几乎无法识别，影响成像系统的分辨率。

In order to study the influence of atmospheric turbulence scintillation effect on synthetic aperture laser radar imaging, based on Kolmogorov turbulence spectrum model, according to the Mellin transform technique and the atmospheric turbulence structure constant model, we derive the logarithmic amplitude variance of the receiver beam propagating in the atmospheric turbulence in slant path. The relationships of logarithmic amplitude with the object height and wave band are analyzed. According to the probability density function of laser echo in the atmospheric turbulence scintillation effect, the synthetic aperture radar imaging without filter is simulated. The numerical conclusions indicate that with the increase of the turbulence intensity, the image becomes fuzzier, especially when the turbulence is closing to saturation, the target can hardly be identified, and the resolution of the imaging system is affected.
