摘要
HJ-1星座光学卫星作为我国环境与灾害监测预报小卫星星座的首发卫星,其运行与应用状况对于后续星座的发展具有重要的理论和实践指导意义。本研究从HJ-1光学卫星的分辨率(时间、空间和光谱)、光谱及幅宽等数据特征入手,综合考虑遥感应用数据要求,全面分析评价HJ-1光学卫星数据可用性。研究表明,两颗光学卫星可基本满足我国及周边国家环境监测与灾害管理方面的主要应用需求,并在其它领域也具有广阔的应用前景。
HJ - 1 optical satellites are to be launched firstly in small satellite constellation for environment and disaster monitoring and forecasting. The status of the operation and application has an important theoretical and practical significance for the development of the subsequent constellation. Based on the data characteristics of HJ - 1 optical satellites such as the temporal, spatial and spectral resolutions , the spectra and the swath width, and considering the requirements of remote sensing application, the authors have analyzed and estamated the usability of HJ - 1 optical satellites comprehensively. It is held that the HJ - 1 optical satellites can meet the principal working needs in China and its neighboring countries in remote sensing application, and will surely have a wide application potential.
