摘　　要：为了实现激光雷达监测海洋赤潮的目的,采用红外激光能较好地反映藻类悬浮粒子密度等信息。分别就海水中水分子、浮游植物、黄色物质、悬浮颗粒与1.064μm激光的吸收和散射特性展开研究,最终构建了1.064μm激光在海水中的探测模型。通过对模型的仿真计算可知,红外激光雷达能有效地探测水下0.8m内的海水水域。结果表明,1.064μm激光水下探测深度可满足监测海洋表层藻类粒子密度的要求。In order to detect the oceanic red tides based on lidar, the infrared laser can be used to reflect the alga particles＇ density effectively. The interaction between 1. 064μm laser and several marine matters, including water, phytoplankton, yellow substance and suspended particulates was analyzed. The detecting model of 1. 064μm laser in the seawater was built. Based on the model and simulation, a conclusion is drawn that the infrared lidar can detect the underwater area within 0.8m effectively so that 1. 064μm laser can satisfy the need of detecting the oceanic alga particles＇ density.
