Multi-Mode Wind Lidar

The multi-mode wind lidar system is constructed based on 1.55μm all-fiber components and comprises four main modules: laser transmitter module, optical receiver module, signal acquisition and processing module, and secondary power supply module. It features three detection modes: ground-based profiling mode, airborne profiling mode, and nacelle measurement mode.
