摘要
依据机载蓝绿激光脉冲的传输过程，分析了激光束向下传输时返回的后向散射波形，采用从返回信号中提取出海水的有效衰减系数ｋｅｆｆ的方法，并利用测深系统海上实验采集的数据，获得了后向散射波形的有效衰减系数的估算值，并对结果进行了讨论．
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 .
