摘　　要：提出了基于机载激光雷达应用于海洋赤潮的监测与预报方法,以检测激光水下后向散射光信号,实现对海洋赤潮藻密度信息的获取.引入赤潮藻散射系数的概念,建立了机载激光雷达的赤潮藻散射系数探测模型.通过仿真计算,证明该模型可以有效评估出赤潮藻密度的大小,进而实现对赤潮消长过程的判断.A method for red tide detection and forecast by airbone lidar is proposed. By detecting the light scattering signal under water,the red tide alga density information is given. A scattering coefficient model for airborne lidar detection of red tide is firstly established through introducing the concept about the red tide alga scattering coefficient. The emulation proves that the model can evaluate alga density and accordingly forecast the growth process of red tide.
