WitrynaBlackbody radiation, temperature, and thermodynamic equilibrium give a tightly coupled description of systems (atmospheres, volumes, surfaces) that obey Boltzmann statistics. They are important because of the compact descriptions of systems that they give when Boltzmann statistics apply, either approximately or nearly exactly. Fortunately, this is Witryna12 kwi 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. In this study, a blackbody-based …
