Effect of the Temperature Field of Target on Infrared Imaging Detection

摘要:

在红外成像探测中,目标温度场会影响探测距离。通过实验,研究了目标红外图像像素数随温度的变化,以及这种变化对红外成像探测距离的影响。根据实验中的像素数统计,计算图像中目标像素点个数在整个红外图像中所占的比例,并分析目标温度变化对目标能量分布的影响。依据对红外成像系统观测等级的划分,对作用距离进行了估算研究,通过仿真和实例计算,验证了温度场扩散对探测距离的影响。

Abstract:

In infrared imaging detection, target temperature field will effect detection range. The change of target infraredimage with the temperature, and the effect of this change on infrared imaging detection range were studied by experimen.tal. According to the number of pixels in the statistical experiment, the proportion of the number of target infrared image’s pixels point in the whole infrared image was calculated, and the effect of target’s temperature change on the energy distri.bution of the target infrared image was analyzed. The effect of distance of system was studied based on the division ofthe observed level of infrared imaging system. Through the simulation and calculation examples, the effect of diffusion onthe temperature field of the detection distance was verified.
