法国遥感卫星SPOT数据1A级预处理技术

航天遥感原始数据的预处理是建立地面数据应用工程运行系统的关键技术之一。在１Ａ级预处理中，需要解决处理任务组织和系统环境支持问题，需要完成数据回放、相对辐射校正、景地理坐标计算作业，这些问题的解决方法对遥感数据处理技术具有一定普遍意义。本文还介绍了一种数据预处理系统。

LEVEL 1A PRE-PROCESSING TECHNOLOGY OF THE DATA FROM FRENCH SATELLITE SPOT

The pre-processing of the remotely sensed raw data accquired from the space is one of the key technologies in the data application ground engineering operation system. In the level 1A pre-processing the following functions should be performed:processing tasks organizing and system environment supports, data ingest, relative radiometric correction, geographic coordinate computation of scene benchmarks, etc. A data pre-processing system is introduced.
