近日,中国资源卫星应用中心组织召开了2016年外场绝对辐射定标试验及结果评审会。环境减灾-1A/1B、资源一号02C、资源三号01/02、资源一号04、高分1/2/4号等在轨卫星的绝对辐射定标系数顺利通过评审并正式发布。为了及时监测卫星载荷在轨辐射响应特性,获取准确的绝对辐射定标系数,中国资源卫星应用中心于2016年8月组织开展了外场定标、验证试验和试验数据处理工作。在定标和验证过程中,分别针对可见光、近红外波段、中红外和热红外波段的传感器,在敦煌和青海湖辐射校正场获取了星地同步观测数据。
Recently, China Resources Satellite Application Center organized and held the 2016 field of absolute radiation calibration test and results review. The absolute radiometric calibration coefficients for environmental mitigation -1A / 1B, Resource No.1 02C, Resource III 01/02, Resource I04, High score 1/2/4 and so on were successfully passed the assessment and officially released. In order to timely monitor the orbital radiation response characteristics of satellite loads and obtain accurate absolute radiation calibration coefficients, China Resources Satellite Application Center organized the field calibration, verification and experimental data processing in August 2016. In the process of calibration and verification, satellite-observational data were acquired for radiative correction fields in Dunhuang and Qinghai Lake respectively for visible, near-infrared, mid-infrared and thermal infrared bands.
