摘　　要：近海层大气湍流对舰船激光通信有重要的影响。本文基于Kolmogorov和Rytov大气湍流理论,推导适用于描述强、弱湍流条件下信噪比及误码率的理论模型,结合舰船通信的物理条件进行数值仿真,同时分析在相应湍流强度下大气湍流对不同波长激光通信性能指标的影响,并提出提高通信质量的措施。The atmospheric turbulence over sea has an important effect on Laser communication between the ships.Based on Kolmogorov and Rytov＇s turbulence theory,this paper derived the theoretic model of the signal-to-noise （SNR） and bit error rate （BER） for the strong or feeble turbulence.It simulated numerically with the parameters of communication between the ships and analyzed the effect of atmospheric turbulence with different wavelength.At the end,the paper advanced the measures for improving communication quality.
