星载大气探测激光雷达技术与应用

Technology and Application of Space-Borne Atmospheric Detection Lidar

本文对国内外星载大气探测激光雷达的原理、技术和应用等情况进行了分析和归纳。星载大气探测激光雷达的发展,是科学需求、探测理论、硬件技术、应用能力波浪式推动和迭代的过程,具有弱周期性。在云和气溶胶方面,多波长、高光谱分辨结合偏振的综合探测将为科学研究提供更精细的微观信息,而小型化微脉冲激光雷达则为星座探测提供了技术基础。在大气成分方面,积分路径差分吸收技术将能提供更精确的数据。激光雷达是对其他遥感系统的有效补充,更加注重廓线探测、空间分辨和测量精度,在水平覆盖、探测效率等方面存在天然不足,激光雷达与其他遥感手段结合,才能构建更加科学的观测体系,为科学研究和遥感应用提供更有力的支撑保障。

In this paper,the principle,technology,and application of space-borne atmospheric detection lidar in China are analyzed and summarized.The development of space-borne atmospheric detection lidar is a wave-like push and iteration process in terms of scientific requirements,detection theory,hardware technology,and application capability,with weak periodicity.For clouds and aerosols,multi-wavelength,high-spectral resolution,and polarized lidar will provide more detailed microscopic information for scientific research,while miniaturized micro-pulse lidar will provide the technical basis for constellation detection.For atmospheric composition,the integral path differential absorption technology will be able to provide more accurate data.Lidar is an effective supplement to other remote sensing systems.It pays more attention to profile detection,spatial resolution,and measurement accuracy.However,it has natural deficiencies in horizontal coverage and detection efficiency.Only when lidar is combined with other remote sensing methods can a more scientific observation system be constructed and more powerful support for scientific research and remote sensing application be provided with it.
