Based on the formation mechanison of targets infrared characteristic, this paper discusses a method to modulate ground target's infrared characteristic through artificial illuminator. The theoretical model of ground targets irradiated artificial illuminator is established, then the targets surface temperature is calculated and measured, and the targets' infrared radiation is calculated and analyzed. The results show that the infrared characteristic of ground targets can be modulated through artificial illuminator, and the effect of modulation is determined by illumination power, time, distance, and incident angle. In general conditions, the effect of modulation is obvious at night, but not in the daytime.
