| 摘 要： | 传感器波段平均太阳辐照度是计算表观反射率等辐射参量的必要参数,是开展定量遥感分析的重要基础。通过中国气象局发布的零大气条件下太阳光谱辐照度数据和遥感数据运营商提供的珠海一号高光谱传感器光谱响应函数资料,计算了珠海一号三颗高光谱卫星上三组传感器的波段平均太阳辐照度。以中国资源卫星应用中心发布的高分一号资料为参考,确定结果具有较高的准确度,可为珠海一号高光谱数据的推广和使用提供参考。

| Abstract: | Band mean solar irradiance of sensor is the necessary parameter for calculating radiance parameters such as apparent reflectance,as well as the base for quantitative remote sensing analysis.By using solar spectral irradiance under zero air mass published by China Meteorological Administration and spectral response functions provided by operator,band mean solar irradiance for COMS1/2/3 sensors respectively onload on OHS-2A/B/C has been calculated.The result is acceptable as compared to GF-1 PMS1/2 data published by China Centre for Resources Satellite Data and Application,and can be referenced for promotion and use of OHS hyperspectral data. |
