| 摘 要： | 文章以“环境一号”B星（HJ-1B）发射前实验室定标为基础，分析了HJ-1B红外相机的星上定标系统功能。利用2009年3次星上黑体定标数据对HJ-1B热红外通道进行星上定标，以青海湖不同时相的美国TERRA卫星MODIS传感器31通道（MODIS-31）数据对HJ-1B热红外通道进行交叉定标，得到了准确的定标系数，最后对两种定标方法进行误差对比分析，为实时准确的获取HJ-1B热红外通道定标系数提供方法借鉴。

| Abstract: | In this paper, the function of onboard calibration systerm of HJ - 1B infrared camera was analyzed based on laboratory calibration. The absolute calibration coefficients of HJ - 1B thermal infrared channel were achieved by three times onboard calibration and cross - calibration of Qing Haihu - data between MODIS - 31 channel and thermal infrared channel of HJ - lB. Finally, the paper compared and analyzed different method errors and precision.This provided method reference for receiving HJ- 1B thermal infrared calibration coefficients well and timely. |
