| Abstract: | According to the transmission of laser beam in seawater, a method of deducing the effective attenuation coefficient ( k eff ) of the transmission from the backscatter waveform of laser beam has been introduced to discuss the k eff of different experiments. A data set obtained by an airborne laser batchmetry system is used in deriving the analysis of k eff . |
