摘　　要：高轨遥感卫星具有“站得高、看得广、盯得久”的特点,具备大幅宽成像、持续凝视成像以及高时效成像能力,可实现对各类紧急观测任务的快速响应。发展高轨海洋遥感卫星,研制面阵凝视型海洋与海岸带光学遥感系统,可填补中国高轨海洋环境动态监测的空白,满足对中国周边海域、近岸与海岛观测以及应急监测的迫切需求。文章通过对高轨海洋与海岸带光学遥感系统的技术特点进行分析,提出了采用大口径低杂光/低偏振/多光谱光学系统、高信噪比提升、高精度星上定标等技术的系统设计方案。据此完成样机研制与系统测试,并结合外景试验,验证了核心指标的可行性,为高轨海洋与海岸带光学遥感系统工程实施奠定了技术基础。The geostationary satellite has the characteristics of"standing high,seeing wide and staring long",and has the capability of large width imaging,continuous staring imaging and high timeliness imaging,which can realize the rapid response to various emergency observation tasks.The developments of high-orbit ocean remote sensing satellites and the array-gazing optical remote sensing system in ocean and coastal zones observation can fill the gap of dynamic monitoring on the marine environment in high orbit in China,and meet the urgent demand for observation and emergency monitoring of the surrounding sea areas,nearshore and islands of China.By analyzing the technical characteristics of the high-orbit optical remote sensing system for the ocean and coastal zone,a system design scheme has been put forward,in which many technologies are adopted,such as a large-aperture optical system with low stray light,low polarization and multi-spectral features,a high improvement in the signal-to-noise ratio,and an on-board calibration with high precision.Based on this,the prototype development and system testing have been completed,and combined with field tests,the feasibility of the core indicators has been effectively verified,laying a technical foundation for the implementation of the high-orbit optical remote sensing system project for the ocean and coastal zone.
