| 摘 要： | 该文描述了基于反射率方法的机载中分辨率成像光谱仪（AMODIS）外定标方法。可见光和近红外波段的17个通道定标结果表明，成像光谱仪两个飞行高度测值的外定标系数是非常吻合的，其相对差为0.19%～3.89%；成像光谱仪关于草地航测的反演值与地面实测值比较，结果也是比较接近的。

| Abstract: | Based on reflectance method,vicarious radiometric calibration of remote sensing data from Airborne Moderate Resolution Imaging Spectrometer (AMODIS) is described. The results show that the calibration coefficients at two flying altitudes from 17 channels of visible and near infrared region were,respectively,in coincidence,and the relative difference was between 0.19% and 3.89%. Also the retrieval values from AMODIS in the model flying experiment were coincided with the observations of surface synoptic station. |
