摘要
20世纪 80年代末以来 ,中国就开始十分重视海洋遥感技术的发展 ,从 1987年起在FY - 1A卫星上就加上了海洋水色通道 ,发展到 2 0 0 2年发射了专门的海洋水色HY - 1A卫星 ;从地面的海洋反射率光谱仪的测量 ,发展到卫星上的水色、水温扫描仪 ;从简单的假彩色合成处理技术 ,发展到多要素、多功能的海洋要素提取和应用技术。总之 ,中国的海洋遥感技术在国际上已有了发言权和一席之地。但在以海洋卫星为主导的立体海洋监测体系 ,高精度分析与定量比测量 ,多平台监测数据同化和技术集成等方面与国际上先进国家比 ,还存在着差距。就以上方面的差距出发 ,文章最后提出了建立稳定运行的海洋卫星体系 ,必须从多方面入手 ,提高海洋遥感精度和开发同化技术研究的应用水平 ,提出了有效建议。
Since eighties, China has paid more attention and makes great progress in space marine remote sensing.Two ocean color channels was added in meteorology satellite FY-1A in 1987, the spatial marine satellite HY-1A was developed and launched in 2002 The Chinese Ocean Color and Temperature Scanner (COCTS) are developed to measure the water leaving radiance from the sea surface reflectance meter. The high technique of satellite data processing and application are developed from simple three color combination technique. In general, China has her own position in this field of the world. Finally, some available suggestions are discussed in this paper, such as developing stable marine satellite operational monitoring system, accuracy analysis and quantity, high frequency and long term monitor data collection, the combination application of multi-sensor and key technique, based on the leg distance between China and developed western countries.
