| 摘 要： | 采用偏振检测方法 ,对机载激光测深实验系统接收到的大动态范围的水下目标反射的激光回波信号的压缩进行了实验研究。结果表明 ,偏振检测方法能压缩激光回波信号的动态范围至少达一个数量级 ,对水下的激光后向散射有较强的抑制作用 ;对探测水下目标反射的激光回波信号的影响不大。

| Abstract: | This paper described apolarization detection method to compress the lager dynamic range of laser returnedsignals in airborne laser bathymetry system. The experimental results show that the methodcan compress the dynamic range of returned signals more than one order, restrain the laserbackscattering largely, and haven′t influence too much on detecting laser returned signals from theunderwater. |
