针对海水光信道的散射效应问题，选择Henyey-Greenstein函数产生散射角，基于蒙特卡洛(MC)仿真方法分析了Ⅰ类水质和Ⅱ类水质信道下，传输距离和接收视场角(FOV)对抵达光信号散射成份的比例特性的影响。分析结果表明: Ⅰ类水质信道下，散射成份只占小于1.2%的比例；Ⅱ类水质信道下散射成份明显增加，此时，FOV的取值对散射成份比例特性的影响明显；尤其在Ⅱ类水质(港口)信道下，当传输距离大于6.0 m时，散射成份几乎占抵达光信号的100%。

Aiming at the scattering effects of seawater optical channel, the Henyey-Greenstein function is selected to generate the scattering angle. Based on the Monte Carlo(MC) simulation method, the effects of transmission distance and field of view (FOV) on the proportion of scattering components of arriving optical signal under caseⅠseawater and caseⅡseawater channels are analyzed successively. The results show that the proportion of scattering components of arrival optical signal under caseⅠseawater is less than 1.2%. The scattering components is significantly increased under caseⅡseawater channels, and the value of FOV has an obvious effect on the proportion characteristics of scattering components. Especially for the caseⅡseawater (harbor) channels, the proportion of scattering components is approaching to 100% when the transmission distance is longer than 6.0 m.
