    Abstract: Near-space wind field detection plays a crucial role in atmospheric science, aerospace engineering, and related disciplines. Accumulating comprehensive wind field data is essential for investigating atmospheric energy transfer mechanisms, improving climate change predictions, and enhancing flight safety. Rayleigh Doppler lidar and resonance fluorescence Doppler lidar, the two main measurement techniques, complement each other. Their integrated deployment enables continuous atmospheric wind field monitoring with high spatiotemporal resolution. This paper introduces the operational principles of both systems sequentially, followed by reviews of global advancements in core technologies. Finally, emerging development trends for near-space wind measurement lidars are discussed.
