| 摘 要： | 环境一号B星红外多光谱相机(简称HJ-1B星IRS)在轨运行过程中受各种因素的影响,其探测性能不断发生衰减,绝对辐射定标可有效地改善遥感器辐射特性的测量精度,从而提高遥感数据辐射质量.文中针对HJ-1B星IRS星上定标系统特点,利用2010年8月地面同步试验数据对IRS热红外通道进行综合辐射定标,修正了原始定标系数,并进行定标系数的真实性检验.结果表明借助地面试验数据进行的综合辐射定标弥补了星上定标系统的不足,获得的定标系数准确可靠,可满足遥感数据定量化应用的需要.

| Abstract: | The infrared multispectral camera(IRS) of HJ-1B is subject to several influences that cause performance degradation while in orbit.Absolute radiometric calibration can effectively adjust the measured radiometric accuracy of the sensor,improving the radiometric performance of remote sensing data.Based on the characteristics of the IRS on-board calibration system,this paper uses data recorded from a test site in August 2010 to carry out a radiometric calibration of the IRS thermal infrared channel,verify the ... |
