摘要

分析了海水通道中纯海水、浮游植物和悬浮颗粒的吸收和散射特性，并研究了光束膨胀对损失的影响。建立了基于生物光学特性的海水通道衰减模型。最后，根据海水通道衰减模型，通过MATLAB仿真分析了不同特性的全球海域衰减特性。得出结论，水下通信的光衰减主要取决于海洋本身的性质。这为水下无线光通信系统的总体设计提供了依据。

Channel simulation analysis of seawater laser communication

In this paper, the absorption and scattering characteristics of pure seawater, phytoplankton and suspended particles in seawater channel are analyzed, and the effects of loss caused by beam expansion are studied. A seawater channel attenuation model based on bio-optical properties is established. Finally, according to the seawater channel attenuation model, the global sea area attenuation characteristics of different characteristics are analyzed by MATLAB simulation. It is concluded that the light attenuation of underwater communication depends mainly on the nature of the ocean itself. This provides a basis for the overall design of the underwater wireless optical communication system.
