In this paper, the thermal imaging response characteristics including temperature response, time response and image illumination were analyzed respectively for the ultra-wide field of view infrared fish-eye warning system and it is found that the system temperature response is linear, and with the process of time, the system output becomes bigger gradually, which fits a cubic polynomial f(t), and it tends to be a fixed value after about 70 min. With the analysis of the gray values of the same target in different positions, it is found that the gray value relative standard deviation is only 2.26 %, which indicates that the target gray values in different positions are nearly equal, and hence it is proved that the system image illumination is uniform, which is consistent with the theory analysis.
