摘　　要：风对民航运行安全有重要影响,结合机场特殊需求,利用激光雷达径向风速反演实际风场有助于快速识别风切变高风险区。研究利用距离高度显示的径向风速反演出机场跑道顺逆风垂直廓线,其反演结果与四波束反演结果有较好的一致性,能够捕捉到低空风的切变信息。利用平面位置显示扫描模式的径向风速反演了水平风场,结果表明风场均匀的假设与实际情况相符,证明了简化算法在机场业务保障中具有可行性。Wind has an important impact on the safety of civil aviation operations.In combination with the special needs of airports,the use of lidar radial wind speed to retrieve actual wind fields can help quickly identify areas with high wind shear risks.In this study,the radial wind speed displayed by range height indicate was used to invert the vertical profile of the airport runway.The inversion result is in good agreement with the four-beam inversion result,and the shear information of the low-level wind can be captured.The horizontal wind field was inverted using the radial wind speed in the scanning mode of plane position indicate.The result showed that the assumption of uniform wind field was consistent with the actual situation,which proved the feasibility of the simplified algorithm in airport service guarantee.
