摘要 星载SAR辐射定标处理是实现SAR定量化应用的重要技术手段,设计并实现基于星载SAR的定标处理与评估系统对进一步完善我国雷达卫星定标处理系统和提高定量化水平具有重要的理论意义和实际应用价值。研究了定标处理流程和系统功能,并根据模块独立化和自顶向下的原则,设计并开发了一个综合性的定标处理与评估系统。该系统可为精密定量雷达图像产品生产提供各种校正参数,并动态监测SAR系统性能。通过实际数据的充分测试和验证,表明系统具有很好的可扩展性和实用价值。 Spaceborne SAR radiometric calibration processing is an important technical method for quantitative application of SAR.Thus,research on spaceborne SAR calibration processing and evaluating system will be of theoretical significance and of practical worth.In this paper,by investigated the flow and systemic function of calibration processing,and based on the principles of model independence and top-bottom design,a synthetic calibration processing system is realized.This system can not only provide the correction parameters for producing quantitative and precise images,but also monitor the performances of SAR system.Testing and validation of real data indicates that the system is expansibility and applicable.
