摘要
南极、北极和青藏高原素有地球三极之称,正经历着巨大变化的"三极"区域既是影响研究全球气候变化的关键区,又是保障国家安全利益的重要战略特殊区。激光测高卫星具有快速获取全球地表高精度三维信息的特点,在极地区域相比其他类卫星其优势更加明显。为满足新形势下"三极"区域遥感观测研究的需求,立足于激光测高卫星,总结了国内外已有激光测高卫星在极地观测方面的现状,分析了激光测高卫星在极地区域的观测需求,探讨了激光测高卫星在极地区域的可观测要素,提出了我国发展极地观测激光测高卫星的相关建议,并对未来极地遥感卫星体系建设给出了初步设想及展望。
Antarctica, Arctic and Qinghai Tibet Plateau are known as the three poles of the earth. The " tri-polar" regions, which are undergoing great changes, are not only the key areas affecting the study of global climate change, but also the important strategic special areas to protect national security interests. Compared with other polar satellites, it has obvious advantages in obtaining high-precision 3 D earth surface information. In order to meet the needs of remote sensing observation and research in the "tri-polar" region under the new situation, based on the laser altimetry satellite, the status of the existing laser altimetry satellites in polar observation was summarized. The observation requirements in polar region were analyzed, and the observable elements of laser altimetry satellite in polar region were discussed. Moreover, the development of laser altimetry satellite for polar observation in China was proposed, the preliminary ideas and prospects for the future construction of polar remote sensing satellite observation system were discussed.
