In order to improve the accuracy of multi-spectral scene simulation, and avoid resource waste of unnecessary
computing, some researches on the radiation influence between buildings during the multi-spectral simulation in the
waveband 3-5μm and 8-12μm have been done, so as to provide theoretical support for whether it is needed to compute
the radiation influence between buildings in the multi-spectral simulation. This paper determines the primary factors that
affect the degree of radiation influence between buildings, determines the effect that the sun direct radiation to the
radiation influence between buildings, derives the computation formula for radiation influence between buildings in a
specific scene from many basic common heat radiation formula and simulates the scene radiation in multi-spectral in the
specific scene. Finally, the importance of radiation influence between buildings comparing to the entire scene simulation
radiation was evaluated based on numerical calculation. The numerical calculation results show that the radiation
influence between buildings in waveband 3-5μm can be ignored when the sun direct radiation exists, which can’t be
ignored in waveband 8-12μm. In the waveband 8-12μm, the radiation influence between nearby buildings is great in
waveband 8μm, 9μm and 10μm, more than 10% comparing to the buildings’ self radiation, which is small in waveband
11μm and 12μm, less than 4%.
