Dynamic simulation of infrared system imaging blur effect caused by carrier platform vibration

The model of infrared system imaging blur effect caused by carrier platform vibration was studied. Considering the theory of infrared system imaging and the vibration regularity of carrier platform, the model of infrared system imaging blur effect caused by carrier platform vibration was established. The pre-generation method of the blur effect texture was studied, on the basis of which the real-time sampling method of the texture mentioned-above was built. Then the infrared system imaging blur effect was simulated dynamically. The degradation degree of the infrared system imaging quality under different vibration conditions was quantitatively analyzed. The results show that, the increase of carrier platform vibration amplitude or frequency would result in more serious degradation of the infrared system imaging quality; Furthermore, the farther the observation distance is, the worse the carrier platform vibration influence on the system imaging quality is.
