For meeting the demand of generating IR sky image in real-time in 3D scene simulation of IR seeker, a method of generating IR sky image was proposed in this paper. Firstly, the key factors that affect sky radiation in IR simulation was analyzed by MODTRAN and IR radiation with different zeniths was calculated according to these factors. The IR sky image was created by method of interpolation to radiance of different zenith and expanding the column vector of IR image. The database of sky radiation profile was constructed to dynamically update sky image in simulation system. According to experiments, instantaneity of the method in this paper is good, and the result of simulation is credible.
Key words： sky radiance; key factors; interpolation; radiance profile; database
