| Abstract: | The radiance measured in atmosphere is affected by the atmosphere.In order to obtain the original radiance of a target,the atmospheric transmission correction should be performed.The basic theory for atmospheric correction in the measurement of infrared radiance of target is introduced.Some methods for obtaining atmospheric transmittance are given,and the accuracy of atmospheric correction in infrared measurement is discussed. |
