Lidar多向风速实时遥测系统

LIDAR WIND-SPEED REAL-TIME MEASUREMENT SYSTEM

采用数字相关检测技术，对Lidar信号进行时空域数据处理和分析，并利用光学摆镜进行水平和俯仰扫描，可实时遥测局部区域范围内轴向、横向和垂直三个方向上的风速。文中详细介绍了时空域离散信号处理的理论计算公式和处理系统结构，对风速测量结果进行了分析和比较。

Digital correlation detection technique is used and Lidar signals are processed and analyzed in the space-time domain. By swinging and scannins of Lidar beams, real-time remote measurement of wind velocities in the radial, horizontal and vertical directions can be realized. The theoretical formulas of discrete signal processing and circuit structure in the system are described, and results of wind-speed measurement are analyzed and compared.
