摘要
机载海洋激光雷达具有高效搜索的能力,已成为海洋环境监测的重要手段。以机载蓝绿激光雷达监测海洋赤潮为研究应用背景,通过检测海洋中叶绿素的质量浓度来实现对海洋赤潮消长信息的获取。在分析海水固有光学性质的基础上,基于生物光学算法,构建了机载蓝绿激光雷达后向散射信号检测的的叶绿素质量浓度监测模型。仿真计算证明该模型能够有效探测出叶绿素质量浓度的大小,为机载海洋赤潮监测增加了一种方法。
With high efficiency and high detection precision, the airborne lidar has become an important means to monitor marine environment. Based on the research background of monitoring red tide by airborne blue lidar, a new method of achieving the growth information of red tide alga is proposed, by detecting the concentration of chlorophyll. By this concept, based on analysis of the optical properties of several important ocean objects and biooptical algorithm, a model is proposed based on airborne lidar detecting backward scattering signals. Simulation proves that the method can monitor the concentration of chlorophyll effectively. It provides a method for red tide detection based on the airborne lidar.
