Abstract :
This article describes the experiment of airborne Fourier transform infrared (FTIR) spectrometer detecting the background radiation of earth and atmosphere. Considering the atmospheric absorbance and emission, the relation between radiation measured by FTIR and surface emissivity was analysed and theoretic expression was given. It was proved that the background radiation lie on four parameters. Measured spectra which collected under various conditions were analysed and spectral characters of background radiation were described.
