空间主动光电遥感现状及发展

Current Status and Development of Space-Based Active Opto-electronics Remote Sensing Technology

空间主动光电遥感技术在空间对地观测和深空探测等领域具有广阔的应用前景,探测对象包括地球和地外天体三维地形、地球植被垂直分布、大气气溶胶与云的垂直分布、大气温湿廓线、大气风廓线和特殊气体浓度等。为系统梳理空间主动光电遥感技术,综合分析了国内外空间主动光电高程探测载荷和大气垂直廓线探测载荷的发展历史和现状,提出了未来我国在多波束单光子三维地形探测、高光谱分辨率激光大气探测、差分吸收激光大气探测、激光掩星大气探测和激光海洋探测领域开展更深入研究的建议。

Space-based active opto-electronics remote sensing technology has been widely used in earth observation and deep-space exploration. Its measurement objects include three-dimensional (3D) terrain of earth and extraterrestrial objects,vertical distribution of earth vegetation,atmospheric aerosol and clouds,atmospheric temperature and humidity profiles,atmospheric wind profiles,specific gas concentration and so on. To systematically sort out the latest technology of space-based active opto-electronics remote sensing,the domestic and foreign development history and current status of space-based active opto-electric elevation detection payloads and atmospheric vertical profile detection payloads are comprehensively analyzed. It is suggested that China should conduct deeper reserch on multi-beam single-photon 3D terrein detection,high spectral resolution laser atmospheric detection,differential absorption laser atmospheric detection,laser occultation atmospheric detection,and laser ocean detection.
