为了了解多次散射对轻霾天气下大气激光通信的影响程度，建立了轻霾天气下大气多次散射的模型，并进行了分析，从理论上证明了在轻霾天气下前向散射对光接收的影响可以忽略。这为设计大气激光通信光收发系统提供了理论依据。

In order to understand how the multiple scattering affecting the atmosphere laser communication in haze weather,the multiple scattering model was set up. After analysis,a conclusion was drawn that in light haze weather,the effect of forward scattering on laser communication could be ignored. The theory can be used in atmosphere laser communication system design.
