| Abstract: | The signal of a target measured by electro-optics detector is attenuated by the atmosphere and affected by atmospheric background radiance. Atmospheric transfer correction is important to the measurement of target's radiation characteristic. The commonly-used atmospheric radiative transfer models and the detecting methods of important atmospheric optics parameters affecting atmospheric radiative transfer were introduced. The atmospheric parameters affecting infrared radiative transfer were analyzed, the analyzed results indict those key atmospheric optics parameters must be measured in the atmospheric transfer correction system. |
