阐述了星载对地测风激光雷达系统对于全球大气气象研究的意义,总结了国际星载测风雷达系统的研究思路。介绍了中国海洋大学在国际上地基、机载、星载这一激光雷达研究思路下,基于碘分子吸收滤波器设计的车载、机载激光雷达系统和相关系统的验证实验,在地基测风系统的基础上建立了532 nm波段基于碘分子吸收滤波器或法布里-珀罗滤波器的Labview星载模拟软件。使用车载系统的实际测量数据对使用碘分子吸收滤波器的模拟测风激光雷达软件在0～3 km和3～20 km的测风精度进行模拟验证,结果表明回波累积脉冲次数在1300次的时候,可以达到星载测风雷达的测量要求。

Abstract

The importance of space-borne wind lidar for the research of global meteorology and its recent development by NASA and ESA were describled. The Ocean Remote Sensing Institute of Ocean University of China (OUC) developed the Doppler Wind Lidar from a mobile system to airborne lidar system, and a simulation software system using LabVIEW for space-borne wind lidar was designed based on the iodine-filter or Febry-Perot filter. The simulation software is testified by the true wind data acquired by the mobile lidar from land-surface to 3 km and 3 km to 20 km respectively, the simulation results show that the requirement of a space-borne wind lidar is achieved after an accumulation of 1300 pulses.
