摘　　要：中国科学院上海光学精密机械研究所研制出机载全固态多普勒激光测风雷达,并成功进行了试验飞行。本文介绍了机载多普勒激光测风雷达的基本参数和探测三维风场的工作原理,并对利用激光回波信号和机载辅助数据反演三维风场的详细算法进行了研究,获得了3 000 m以下高度具有较高精度的三维风场,同时用经纬仪气球测风法进行了对比验证实验,验证了机载多普勒激光测风雷达测量数据的准确性。Shanghai Institute of Optics and Fine Mechanics of Chinese Academy of Sciences developed and validated an airborne all fiber coherent Doppler lidar for wind measurement. In this paper,basic lidar parameters and operating principles of wind measurements are introduced,and the wind field inversion algorithm by using laser echo signal and airborne auxiliary data is also studied. The three-dimensional wind field with high precision at an altitude less than 3 000 m obtained from airborne experiment was compared with the balloon theodolite measured wind speed to verify data accuracy.
