“委遥二号”卫星长波红外通道在轨辐射定标
|
摘要
"委遥二号"卫星作为中国整星出口委内瑞拉的第二颗遥感卫星,搭载了一台高分辨率相机和一台红外相机,红外相机提供60m像元分辨率的2个长波红外通道。文章针对长波红外通道,采用星上黑体定标方法获得内定标系数,以具有较高绝对辐射定标精度的日本气象卫星H8作为参考传感器进行交叉定标,获取相机长波红外通道内外定标转换系数,最后通过场地实测数据来进行验证。结果表明,通过星上定标和交叉定标相结合的方式获取的绝对定标系数与地面测量计算得到的绝对定标系数相比,入瞳处等效亮温误差在1.5K以内,满足热红外通道绝对定标要求和数据使用要求。
VRSS-2 satellite is the second remote sensing satellite exported to Venezuela by China as a whole satellite, the satellite is equipped with a high resolution camera and an infrared camera(IRC), the IRC camera has two long wave infrared channels with 60 m resolution. As to the long-wave infrared channel, the calibration coefficients are obtained by combining on-board calibration with cross-calibration. Comparing with the calculated results of measured data, the results show that the equivalent bright temperature error of entrance pupil is within 1.5 K, meeting the absolute calibration and data usage requirements of long-wave infrared channel.
