摘　　要：大气颗粒污染物严重影响人类健康以及生态系统可持续发展,研究光学遥感测量技术下大气颗粒污染物监测方法,基于光学遥感测量原理,利用差分吸收激光雷达技术以脉冲激光作为光源,通过分子吸收截面和波长关系计算获取大气颗粒污染物气体颗粒物分子、散射物浓度、距离和颗粒物种类等信息,依据以上信息利用最小二乘法通过数据拟合方式对大气中颗粒污染物实施浓度反演检测,实现大气颗粒污染物实时监测。该方法在不同天气下均可精准监测大气颗粒污染物浓度,且加入不同大小白噪声后,均可保持较高的监测精度。Atmospheric particulate pollutants seriously affect human health and the sustainable development of ecosystems.This paper researches on monitoring methods of atmospheric particulate pollutants under optical remote sensing measurement technology.Based on the principle of optical remote sensing measurement,differential absorption lidar technology is used with pulsed laser as the light source.Wavelength relationship calculation obtains information on atmospheric particle pollutant gas particles,particle concentration,distance,and type of particulate matter.Based on the above information,the least square method is used to perform concentration inversion detection on atmospheric particulate pollutants through data fitting to achieve atmospheric particles.Real-time monitoring of pollutants.The experimental results show that the method can accurately monitor the concentration of atmospheric particulate pollutants in different weather,and can maintain high monitoring accuracy after adding white noise of different sizes.
