摘要
为了满足定量遥感对海洋水色遥感仪器定标精度定期监测的需求,提出海洋一号(HY-1)C/D卫星在星上配置具备高光谱分辨率与高辐射定标精度的定标光谱仪的设计方法,实现对同一卫星平台载荷设备的交叉定标。根据交叉定标基本原理,给出HY-1C/D卫星在轨实现交叉定标的流程设计,指出星上定标光谱仪作为参考遥感器需要满足的设计要求,并从工程实际角度对在轨交叉定标精度进行了预估。结果表明:在轨同平台交叉定标设计能够有效提升光学遥感器之间的交叉定标精度。
For fulfilling the requirements of quantitative remote sensing,the calibration precision of the ocean color remote sensing instruments should be monitored at regular intervals.Therefore the cross-calibration method is proposed,which a spectrograph with high spectral resolution and high radiometric calibration accuracy is equiped to monitor the other instruments on the same satellite platform,is designed by HY-1 C/D satellite.According to the fundamental principles of the cross-calibration method,the on orbit design process of cross-calibration method is provided by HY-1 C/D satellite.Then the desin requiements of the spectrograph is given,and the precision of the cross-calibration method is estimated from a engineering practice point of view.The result shows that this design method can effectively improve the the precision of the cross calibration method for the instruments based on the same satellite platform.
