Research of radiometric calibration system for spaceborne SAR based on workflow

在对原有星载SAR辐射定标处理系统的开发和认识的基础上,分析星载SAR辐射定标处理系统的领域需求及辐射定标数据的处理流程,并对工作流技术及工作流管理系统机制进行研究。在现有的SAR辐射定标处理系统中引入工作流技术及设计思想,实现系统处理的控制逻辑与具体的实现逻辑分离,及辐射定标数据处理的自动化或半自动化,提高数据处理的效率以及系统的灵活性和适应性。

On the basis of the development and knowledge of the original radiometric calibration system for Spacebome SAR, the domain requirement ofradiometric calibration system for Spacebome SAR and the data process flow of the radiometric calibration system is analyzed,, and the technology ofworkflow and the mechanism of workflow management system technology are researched. After introducing the technology of workflow into the current radiometric calibration system, the control logic is separated from the concrete implement logic, and dataprocess automated or semi automated is realized. And the efficiency, flexibility and adaptability of the system are improved.
