| 摘 要： | 介绍了机载傅里叶变换红外(FTIR)光谱仪测量地球大气红外背景辐射的实验过程，对地球/大气的红外背景辐射进行了详细的分析，给出了描述这一辐射过程的理论表达式，证明红外背景辐射主要取决于地表温度、地表发射率、大气透过率和大气温度这四个参数。在理论分析的基础上，对不同观测高度、不同地物背景的实测光谱进行了对比和分析，得到了红外背景辐射的光谱特征。

| Abstract: | The present article describes the experiment of airborne Fourier transform infrared(FTIR) spectrometer detecting the background radiation of earth and atmosphere.Considering the surface radiation and atmospheric absorbance and emission, the expression of radiations measured by airborne FTIR is given.It is indicated that the background radiations depend on four(parameters:) surface temperature,surface emissivity,atmospheric transmission and temperature.Based on theoretic analysis the measured spectra are compared and analyzed according to the differences in altitude and surface.Spectral characters of infrared background radiation are described. |
