飞机目标的红外建模与探测器成像

摘要

基于红外物理学、热传递学,分析了飞机飞行过程中的主要辐射源.运用商业软件FLUENT,计算得到了飞机温度场和辐射场分布.综合大气透过率、探测器响应等因素影响,推导导引头探测器的基本教学模型.最后在搭建OpenGL软件平台的基础上,通过实验得到了导引头探测器接收到的飞机红外辐射图像.%Infrared imaging - guided missile attacks on aircraft research process, need to generate the infrared image of target and the aircraft missile infrared detector simulation are presented. Based on infrared physics, heat transfer stud-y, the sources of main aircraft flight with the use of commercial software FLUENT are analyzed, temperature and radia-tion field distribution of the aircraft are calculated. To integrate atmospheric transmittance, detector response and other factors basic mathematical model of the seeker detector is derived. Finally, based on building a software platform of OpenGL, the infrared radiation image of plane target is obtained which the seeker detector receives through experiments.
