以 1 4 :0 0时离水辐亮度作为背景光强度 ,模拟 35 5 nm激光雷达测量不同深度水层叶绿素 a荧光的信噪比。分析体积衰减系数 c、辐照度衰减系数 k、散射系数 b和透明度盘深度 (SDD)的关系。最后模拟 5 32 nm激光雷达测量悬移质浓度的最大测量深度和误判率小于 1 0 %时的最大海底探测深度随
With water leaving radiance at 2 pm as background light intensity, the simulated signal to noise matio vs measured water depth is given when the 355nm laser is used. The relations of SDD with beam attenuation coefficient c, irradiance attenuation coefficient K and scattering coefficient b are given. Finally, the maximum depths are calculated for measuring the concentration of suspended matter and the coastal depth when the bottom misjudgeme rate is less than 10% in the sea with different SDDs when the 532nm laser is used.
