| Abstract: | 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. |
