激光雷达监测海面溢油遥感理论

超连续谱激光在保持激光原有的高能量密度和良好的方向性的基础上,还具有较宽测量谱段的特点,因此与传统的被动式遥感方式相比,超连续谱激光雷达具有很多独特的优势。在海面溢油探测领域,对溢油事故的发生进行及时而准确的监测是十分重要的,当前采用的遥感探测技术均存在各种缺陷,而超连续谱激光雷达能够在夜晚和白天持续工作,且由于探测信号为回波信号,因此能够实现较大的探测距离和较高的遥感精度。本文主要从海面溢油监测现状、大气对激光传输的影响以及海面溢油高光谱遥感原理入手,对激光雷达海面溢油遥感理论进行了介绍。

Theory of remote sensing for lidar monitoring of oil spill on sea surface

On the basis of maintaining the original high energy density and good directionality of the laser,the super-continuous spectrum laser has the characteristics of a wider measuring spectrum.Therefore,compared with the traditional passive remote sensing method,the super-continuous spectrum laser radar has many unique advantages.On the surface of the oil spill detection field,the oil spill accidents timely and accurate monitoring is very important,the use of remote sensing detection technology there are all kinds of defects,and the continuous spectrum of laser radar can at night and continue to work during the day,and the detection signal for the echo signal,therefore can achieve large detection range and high precision of remote sensing.This paper mainly introduces the theory of lidar remote sensing of oil spill from the aspects of the monitoring status of oil spill on the sea surface,the influence of the atmosphere on laser transmission and the hyperspectral remote sensing principle of oil spill on the sea surface.
