激光雷达在机场低空风切变探测中的应用

Development of lidar in detection of low altitude wind shear

简述了低空风切变及传统探测手段的局限,结合我国香港国际机场的最新研究进展,对多普勒激光雷达的测风原理、低空风切变探测中的自动识别算法及预警系统进行了综述,最后介绍了风切变探测目前存在的问题及最新发展:高性能、人眼安全激光等激光雷达新技术以及数据产品的开发利用是未来研究的重点。

The low altitude wind shear and the limitation of traditional detection techniques are reviewed. Taking the latest developments of wind shear alerting services at Hong Kong international airport as an example, the principle of wind field detection,automatic detection and alerting of wind shear are overviewed. It seems that the high perform ance, eye-safe wind lidar and the exploration of its data are th~ key points for wind shear detection in the future.
