海面舰船多波段动态红外图像仿真

摘要

More and more infrared imaging detectors are used by infrared guidance weapons,it will menace the security of surface naval vessels,so the infrared image simulation of targets becomes more and more important. Based on the heat transfer model of naval vessels, the transient surface temperature of various parts of ship was simulated. The three-dimensional geometrical configuration of the target was made by the method of computer graphics. Considering the effect of environment,sky,sun,relative location between detector and target and atmospheric transmission on the infrared characterization of target, it simulated multiple-band, transient and realistic infrared image.%由于目前红外制导武器越来越多地使用红外成像探测器，对水面舰船形成了越来越严峻的威胁，所以对于目标的红外热像的仿真就显得由为的重要。在建立舰船目标动态传热模型的基础之上，模拟出舰船各部位的表面瞬时温度分布，利用计算机图形学的方法建立出舰船目标的三维几何构形，并综合考虑了周围环境、太阳、目标与探测器相对位置以及大气传输对目标红外特征的影响，模拟出舰船多波段的具有较强真实感的红外热图像。
