Web7 sep. 2010 · Aside from being a perfect absorber for all incident radiation, the blackbody has other important features. Standard texts (Siegel and Howell, 2010; Modest, 2003) show that because the blackbody absorbs the maximum possible radiation at each wavelength and from each direction, it also emits the maximum total amount of radiation, and the …
Web12 apr. 2024 · Infrared signature of targets is one important approach for target detection and recognition. When measuring the infrared signature of a target in the atmosphere, it is necessary to take the atmospheric transmittance and atmospheric radiation between the measured target and the observer into account.
