| 摘 要： | 临近空间风场的探测，在大气动力学研究和提高数值天气预报的准确性，以及航空航天保障等方面具有重要意义。研制基于瑞利散射双边缘技术的60 km多普勒激光雷达用于临近空间大气风场的测量。激光雷达主要分为垂直指向测量系统和两台斜指向测量系统。工作波长355 nm，探测距离15~60 km。为验证系统的可靠性和积累风场观测数据，于2014年下半年进行了外场实验，并与当地的探空气球数据进行对比，结果显示60 km瑞利多普勒激光雷达风场测量数据与探孔气球数据具有良好的一致性。

| Abstract: | The near-space wind measurement is important to atmospheric dynamics, numerical weather prediction and guarantee of aerospace system. A 60 km Rayleigh Doppler lidar was developed to measure the wind of near space. This lidar was based on theory of the double-edge molecular technique. The system included three independent subsystems:one points to the zenith; the two others were tilted at 30 from the zenith with eastward and northward pointing, respectively. It emited 355 nm laser and could measure the wind within 15 km to 60 km. To validate the performance of the lidar and achieve wind data, field experiment of three months was carried out in the second half year of 2014, comparison of the wind data which showed good agreement with radiosonde. |
