摘要
大气中目标辐射特性的测量必然受到大气的影响,为了得到目标本征的辐射特性,必须对大气进行修正.介绍了红外目标辐射测量中的大气透过率修正原理和必要性,给出了几种获得外场大气透过率的方法,并对其大气修正精度进行了讨论.
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.
