为了选择多光谱遥感波段,我们利用了实验室和野外的测试资料研究了十五种地物的光谱反射比,运用T检验、S法和游程检验等数理统计方法,进行了计算机数据处理和分析。对所分析的地物进行多光谱遥感的适宜波段为: O.44—0.51,O.53—O.62,0.63—O.70,0.74—0.80微米。其中最后一个波段可能还要向较长方向延伸。 所选出的多光谱遥感波段与国外一些重要的航天活动所采用的光谱段相当一致。
In order to select the multi-spectral remote sensing band, we used the laboratory and field test data to study the spectral reflectance of fifteen kinds of ground objects. Using mathematical statistics such as T-test, S-test and run-length test, we carried out computer data processing and analysis . The appropriate bands for multispectral remote sensing of the features analyzed are: O.44-0.51, O.53-O.62, 0.63-0.70, 0.74-0.80 microns. The last band may have to extend in the longer direction. The selected multispectral remote sensing band is quite consistent with that of some important foreign space activities.
