激光雷达测量海水光学水质参数

The Estimation of Seawater Turbidity Parameters by Lidar

对于垂直均匀分布海水，提出了利用机载海洋激光雷达数据估计系统的有效衰减系数、海水的体积吸收系数、体积衰减系数和体积散射系数的方法．并根据海上机载试验获得的数据对上述方法进行了验证；对垂直非均匀分布海水条件下海水参数的估计问题进行了初步探讨．

For uniform mixing of seawater within the vertical column, techniques have been developed for the estimation of the effective attenuation coefficient of the system and the volume absorption coefficient, volume attenuation coefficient and volume scattering coefficient of the seawater by the data collected from tests. For nonuniform mixing of seawater within the vertical column, the estimation of the characteristic parameters of seawater is discussed. The techniques developed can be used for quick detection, mapping and monitoring of unusual water turbidity in the ocean. Compared with the conventional manual shipborne method, the method proposed has a much higher efficiency.
