| 摘 要： | 为了促进中波红外面阵遥感相机遥感数据的应用,提出了一种在轨相对辐射定标方法。该方法根据两点定标原理,以中波红外面阵遥感图像数据为基础,利用在轨其他卫星数据获得相机入瞳处辐亮度,计算出非均匀性系数,从而实现在轨相对辐射定标。它为同类红外面阵遥感相机在轨相对辐射定标提供了一种新的思路,同时也可作为星上黑体标的一种校验手段。

| Abstract: | In order to improve the remote sensing data application of the mid-wave infrared area-array remote sensing camera,one relative radiometric calibration method is put forward.Based on the two point calibration principle,this method makes the onboard relative radiometric calibration which calculates the heterogeneous coefficient using the entry pupil radiance data of other on-orbit satellite.This method provides a new way for the infrared area-array remote sensing camera on-orbit relative radiation calibration,and can be a verification method for the onboard blackbody calibration. |
