摘要
临近空间风场探测在大气科学、航空航天等领域具有重要意义;积累临近空间风场探测数据对理解大气能量传输、改进气候变化预测、提升飞行器安全性等方面非常关键。瑞利多普勒测风激光雷达和共振荧光多普勒激光雷达作为临近空间风场测量的两种主要手段,各有所长,二者相互协同能够实现临近空间风场的高时空分辨率连续测量。文章介绍了这两类激光雷达的基本工作原理,围绕关键技术对两类激光雷达的国内外研究进展进行梳理总结,并对临近空间测风激光雷达的发展进行了展望。
Near-space wind field detection is crucial for atmospheric science,aerospace engineering,and related disciplines.The long-term accumulation of comprehensive wind field data is essential for investigating the mechanisms of atmospheric energy transfer,improving climate change predictions,and enhancing the safety of aerospace operations.Rayleigh-Doppler lidar and resonance-fluorescence Doppler lidar,the two primary measurement techniques,are complementary in their capabilities.Their combined application enables continuous monitoring of atmospheric wind fields with high spatiotemporal resolution.This paper first outlines the operating principles of both lidar systems,then reviews global progress in key technologies,and finally discusses future development prospects for near-space wind field measurement using lidar.
