| 摘 要： | 针对近海平面大气湍流的特点,采用多相位屏法,对平面波在不同湍流强度下的近海平面的传播进行了数值模拟。对最终的能量分布与在真空中传播相同距离的传播结果进行了比较。结果表明,湍流对光波强度的影响显著,且湍流强度越大,光波强度起伏越大。

| Abstract: | Aiming at the characteristic of atmospheric turbulence near sea-level,the plane wave transmission in different turbulence intensity is simulated with the method of multi-phase-screen.Compared the final result propagated at the same distance in vacuum,it is found that the impact of turbulence to the intensity is significant.And the intensity of turbulence is greater,the fluctuation of the light intensity fluctuated is greater. |

| Keywords: | near the sea surface simulation of wavefront phase-screen Intensity distribution |
