The cooperative target temperature is one of the important factors that affect the direction jamming effect. The jamming experiment of mid-infrared laser to IR imaging guiding system was carried out,and the object extraction and tracking in different jamming laser intensities and different target temperatures are obtained. Based on the experiment data,the impact of target temperature and jamming laser intensity on IR direction jamming effect was investigated and analyzed. The results show the jamming effect depends on the temperature of target. When the target temperature is higher,the mid-infrared radiation is stronger and the needed jamming laser intensity is higher. Because the IR radiation intensity of target affects the image segmentation threshold and the saturation and crosstalk of guidance image,it will affect extraction and tracking of the object.
