摘要：
This paper covers the design and initial performance analysis of the radiometric calibration pipeline software for the EO-1 Advanced Land Imager (EO-1). The design and implementation of the software and of the radiometric calibration database are discussed. Radiometric calibration data were gathered in the laboratory during integration and test and were used for initializing the database. This database will be updated in the future with data collected on orbit. Initial performance results have been obtained after applying the radiometric calibration to imaging data collected during ALI integration and test and ground calibration. During the initial tests it was noted a few detectors leaked energy into other detectors, thereby requiring special calibration processing for the affected detectors. The handling of this anomaly is discussed, and the initial performance results of the calibration pipeline with the anomaly corrections will be shown.
