摘要：In this paper, based on analysing action between magnetoelectric wave through the atmosphere andthe ground targets each other, mathematical model of the relationship between the ground targets spectral dataand ATM data is derived from theory, and the physical significance of correlation parameters are given .According to ATM data(DS-1268 Scanner) and the spectral data of the field synchronization measurements (IRISSpectroradiometer) at three test fields(Goldsea lake,Gaoyang and Anxin count.y), by using the analysis methodof the statistical regression,the linear regression equations between the ON of each band of ATM(total twelvebands) and the refl ec tance brightness of the !Jl'ound correspondence wave length are obtained under all kindsof conditions, (such as different test fields, periods, flight heights and detection angles etc.). Taking advantageof this quantitative relationship equation, the original images of ATM are directly transformed intothe ground efficient reflectance brightness images.In the transformation procedure,the atmospheric transmittanceand path's radiance don't need to know. The efficient reflectance hrightness images is able to reflectthe ground targets spectral properties. Therefore, the effects of the atmosphere between the ground and theDS-1268 sensor are eliminated,and the image order is apparently improved. Moreover,the relationships betweenthe atmospheric transmissivity and flight heights, detection angles and the atmospheric transmissivity arediscussed
