摘要
从红外辐射和热传导基本定律出发,综合考虑目标实际结构、太阳辐射、天空长波辐射、气动加热及周围环境辐射等因素的影响,依据空中快速目标热辐射特性,分析气动加热对飞机蒙皮辐射的作用,运用等效热阻对内热源部分进行估算,突出发动机传热部分对飞机整体辐射产生的影响,并建立一种可靠实用的空中飞机红外成像仿真模型,仿真过程中结合对空实拍红外图像进行动态调整,目标模拟结果真实感较强。
Based on the radiation characteristic of air speedy object, taking into account the synthetic influence factors of the real configuration of object, sun radiation, space long-wave radiation and the environment radiation around object, a further study for the effect of scarfskin pneumatic heating up, used equivalent resistance to estimate inner heat-resource and gave prominence to the influence on scarfskin radiation caused by engine heat-scattering, a logical and effective IR imaging simulation model for airplane is presented in this paper. The parameters of simulating process were adjusted by combined with the real airplane infrared image, and the experiment infrared image is better.
