摘　　要：分析激光束在海水光学信道中的吸收特性和散射特性,研究在不同波长下的不同杂质和不同杂质浓度与信道衰减特性关系,建立了激光信号海水信道传输模型。利用该模型,根据实际系统参数对波长530nm的信号传输特性进行了仿真分析,得到了不同波长时的系统接收功率范围,及530nm波长时系统在不同灵敏度下的传输距离。Firstly, absorption characteristics and scattering characteristics of laser beam in the sea of optical channel are analysed in this paper, and the relationships of channel attenuation characteristics and different composition and the concentration of different components in the wavelength of light are researched, then seawater channel transmission model of laser beam is established. After that, the channel of signal transmission characteristics in 530nm wavelength are simulated and analysed in using the model and parameters of actual system, then the range of system received powers of different wavelengths and system transmission distances of different received sensitivity in 530nm wavelength are gotten.
