Abstract:
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 capability. 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.
