This paper discusses the effects of total irradiance, atmospheric transmittance and range radiation brightness on remote sensing data. Derived from the different height of the range radiation brightness expression. The observations of the above three parameters in different bands in the visible and near-infrared spectral regions are given in three different regions. The corresponding atmospheric modes were used to calculate the atmospheric transmittance and radiant intensity at different altitudes. The total radiation brightness, target intrinsic radiation brightness and range radiation brightness received by remote sensors in different atmospheric conditions and at different altitudes are estimated at 0.4-0.5, 0.5-0.6, 0.6-0.7 and 0.7-1.1 μm. The relationship between the total radiation brightness and the range projection brightness and the target reflectance is given. The relationship between these data and the atmospheric conditions is analyzed.
