摘要
论述了激光雷达的结构、分类以及不同种类激光雷达的工作原理。跟踪激光雷达最新发展和应用,根据探测物质的不同,分别讨论了激光雷达在探测气溶胶、云、边界层、温度、能见度、风、大气成分、水汽和钠层方面的应用,综述了目前国外星载激光雷达的发展和新的应用动态。进一步讨论了在激光雷达探测中存在的问题和今后的发展趋势,认为激光雷达将向多波长、多探测功能、商业化、区域化及全球化方向发展,它在气象与环境监测中正在发挥越来越重要的作用。
The structure,classifications and principles of different laser radars were introduced.The latest development and application of laser radar were reviewed.According to the difference of detecting substance,applications of laser radar in sounding aerosol,cloud,boundary layer,temperature,visibility,wind,atmospheric compositions,water vapor and sodium layer were analyzed.The latest development and application of spaceborne laser radar at home and abroad were summarized.Furthermore,the existing problems and perspectives of laser radar were discussed.Laser radar will become multi-wavelength,multi-detection function,commercialization,regionalization and globalization,and it plays an important role in monitoring meteorological and atmospheric environment.
