摘　　要：船载卫星遥感图象处理系统是针对南极考察气象航线预报、冰区航行的海冰预报和导航需要而研制的船陆两用多功能软件系统。采用了最新的 DEL PHI可视化软件开发工具 ,开发了用于 WINDOWS98环境下的 32位的程序 ,并针对接收系统开发了 WINDOWS设备驱动程序 ,提高了在 WIND0 WS98多任务环境下 ,接收程序的实时性和可靠性 ;采用面向对象的程序开发方法和开放式的体系结构 ,便于功能的更新和提高 ;采用 SGP4/SDP4轨道模式及两行元素的轨道参数计算出卫星星下点的位置 ,实现了在 1 A图象上计算逐点经纬度的快速动态定位和图象显示的功能 ;采用迭代法利用电子地图网格数据 ,在接收的卫星云图上迭代套上地形及海岸线。组成了适合船陆两用的多功能快速灵活的图象处理系统 ,可以在 1～ 2分钟瞬间内完成一幅图的定位套网格和套地形线的工作。解决了南极海冰监测和冰缝、水道预报的难点。可以使图象上下滚动、左右移动、任意放大、缩小和剪取 ;可以随着鼠标的移动显示出图上任意一点的经纬度 ;能够在图上标出任意目标物 ,如船位、站位、岛屿等等 ;能够方便地在图上画出航线 ,直观地判断船所处的位置和航线周围的气象和海洋环境状况 ;解决了在茫茫海洋和冰区中航行找不到参照物时的困惑 :能够输出任意大小的 2 4位真?WT5BZ]The satllite remote sensing image processing system described in this paper can be used both on ship and on land and is developed for the purpose of ship route weather forecast of Chinese Antarctic Expedition and sea ice forecast and navigator in Antarctic sea ice region. Adopting the new quick visual programming software DELPHI, developing a 32-bit program suitable to run under the Windows'98 32 bit environment. the nwly devloped receiving system using the WINDOW RXD technology, improving the reliability of real time receiving under the multi task environment under WINDOWS 98. The using of object oriental programming method and open system structure makes it possible to improve and renovate it's function. Using SGP4/SDP4 orbit model and two line elements of orbit parameter to compute the latitude and longitude of the satellite's sub satellite point then developing the program to compute the latitude longitude of all points on the frame line decided by the sub satellite point. Realizing the function to find out every point's latitude and longitude on the 1A image directly and dynamically and completing the quick locating and image displaying function. Using SGP4/SDP4 orbit model and two line elements of orbit parameter to compute the latitude and longitud of the satellite's sub satellite point then developing the program to compute the latitude longitude of all points on the frame line decided by the sub satellite point. Realizing the function to find out every point's latitude and longitude on the 1A image directly and dynamically and completing the quick locating and image displaying function. Using iterating method to draw coastal lines and topography lines on the 1A image according to the electronic map data. this quick and flesible multi function system can be used not only on the ship but also on the land and can display and adding latitude longitude lines and topogsaphy lines in 1-2 minutes. Resolving the difficulty to monitoring Antarctic sea ice and forecast of sea ice slot and free wa
