| 摘 要： | 采用修正Rytov方法和近似理论计算了球面波在湍流大气中传播的闪烁指数，并与实验结果进行了比较，发现在弱起伏和中等湍流起伏区修正Rytov解与实验结果符合得良好，而在饱和区采用考虑内尺度效应下的近似理论结果更符合实验结果。

| Abstract: | Based on the modified Rytov method and asymptotic theory, the scintillation index for the spherical wave propagation through the atmospheric turbulence is calculated, and the numerical results compared with the experimental measurement is given. It is found that the results obtained by the modified Rytov method are in good agreement with the experimental measurement in weak and moderate fluctuation regions, but in the saturation region, the results obtained by the asymptotic theory for which the effect of the inner scale of the turbulence is considered show good consistency with the measuring data. |
