文章针对红外相机双面镜旋转多元并扫成像方式的特点,对其相对定标算法进行了研究.首先分析了探元A/B面响应差异,然后介绍了算法原理,采用不同的定标算法获得了定标校正系数,并对定标数据和在轨图像进行了相对辐射校正,验证了算法的正确性和结果的有效性,最后在定标系数校正的基础上,进一步改进了像质.

Infrared camera employed the image mode of double-sided mirror scan whose characters must be recon-sider carefully. Calibration data were analyzed firstly in this paper. Then, the calibration coefficient was obtained by dif-ferent algorithms presented previously. The coefficient was used to correct the calibration image and on-orbit image. Fi-nally, the validation and accuracy of the calibration algorithm was showed.
