针对民航机场风切变探测与预警, 研制了一种三维激光测风雷达, 采用全光纤脉冲相干探测体制, 结合独特的二维光电扫描球结构, 以及新的下滑道扫描策略, 以实现下滑道迎头风与侧风切变的同时测量.2018年3月至11月, 利用该雷达在多种工作模式下对攀枝花机场上空及周边大气风场与风切变进行了探测试验.在3月至5月大风季节期间, 机组报告的风切变均成功被雷达探测.对一次典型个例进行分析, 验证了所研制的三维激光测风雷达在地理气候复杂的高原机场风切变探测的有效性.

For wind shear detection and early warning in civil aviation airport, a three-dimensional lidar was proposed. The lidar adopts pulse coherent detective way of all-fiber, a unique spherical 2D photoelectric scanner and an innovative glide scanning strategy, which realizes the simultaneous measurement of head wind and crosswind shear of glide path. The lidar was tested at Panzhihua Airport from March to November in 2018, which observed the detailed distribution of atmospheric flow and wind shear over and around the airport using a variety of working modes. During the wind season from March to May, the wind shear reported by the crew was detected by the lidar. The most serious case was analyzed, which proved the effectiveness of the 3D lidar in detecting wind shear in the altitude airport with complex geography and climate.
