| 摘 要： | 星载激光测高技术是对地观测系统中最为核心和前沿的信息获取技术之一,因其具有探测方向性好、测距精度高等特点,在地球科学领域中体现出了巨大的应用潜力。在ICESat/GLAS测高地面数据处理系统的基础上,针对将于今年发射的高分七号卫星的载荷特点,设计了一套星载激光测高地面数据处理系统软件。该软件可实现对星载激光测高数据的地面处理并生成3级数据产品,包含激光能量计算、波形分解和激光脚点定位等,以及相应各级产品的数据质量控制处理。利用高分七号仿真数据对该软件进行相应的性能测试,测试结果表明:该系统软件基本满足需求,已初步具备星载激光测高地面数据处理能力。

| Abstract: | Satellite-borne laser altimetry is one of the most important and advanced information acquisition technologies in the earth observation system. It has shown great application potentials in the field of earth science because of its characteristics such as good detection direction and high ranging accuracy. Based on the ICEsat/GLAS altimetry ground data processing system and in terms of the load characteristics of the Gaofen-7 (GF-7) satellite which will be launched this year, a set of system software for the ground data processing of satellite-borne laser altimetry is designed. The software can process the ground data of satellite-borne laser altimetry and generate level-3 data products, including laser energy calculation, waveform decomposition, laser footprint positioning, as well as the data quality control and processing of the corresponding products at all levels. The simulation data of GF-7 are used to test the performance of the software. The results show that the system software basically meets the requirements, and has the preliminary capability of processing the ground data of satellite-borne laser altimetry. |
