摘要:

资源一号02C全色/多光谱传感器数据在国民经济建设中有着广泛的应用, 而精确的绝对辐射定标系数决定着其应用的广度与深度。在轨场地定标方法是获取高精度定标系数的有效方法之一。利用敦煌辐射校正场,基于地面同步测量实验,通过两点法对资源一号 02C卫星全色/多光谱传感器进行在轨绝对辐射定标。并使用新疆靶标2012年7月23日实测数据进行定标系数的验证工作。结果表明:利用两点法所得定标系数可靠性高,可满足遥感数据定量化应用的需要。

Abstract:

ZY-1 02C panchromatic multispectral sensors (PMS) data has made an important role in national development. The calibration coefficient is the key to the breadth and depth of the application. The field calibration method is an effective way to the problem. A field calibration experiment of ZY-1 02C PMS was performed by the China Center for Resources Satellite Data and Application at the Dunhuang site during August 2012. The two-point calibration method was used to obtain PMS absolute calibration coefficients. The results were validated by the data of July 23, 2012 at the Xinjiang target site. It shows that absolute calibration coefficients are highly reliable and enough to meet the requirements of quantitative applications.

Key words: ZY-1 02C, panchromatic multispectral sensors, radiometric calibration, two-point method
