摘　　要：该文主要讨论了实时红外目标仿真的原理和实现方法。该文首先对目标热平衡过程进行原理分析,引进一种专业的工程有限元热分析软件femap,通过有限元建模和精度高的热分析功能,实现目标的3维建模及辐射模拟计算,并通过云图显示处理结果生成实时IR仿真场景。对femap的功能进行了比较深入的研究,并在原理上、实验上给出了验证结果,显示femap应用到IR目标仿真能够充分应用其建模过程工作量小,计算速度快,精度高的特点。The theory and method in real -time IR target image generation for computer simulation are issued in the paper. The theory of target heat balance is analyzed and a new method for the infrared scene simulation using the professional finite - element thermal analysis software femap in engineering is presented. IR scene imagination is generated by the nephogram technology importing the result after 3D target modeling and radiation analysis using femapg mighty finitely generated module and highly accurate thermal analysis. The software femap is researched deeply and also proved on theory and experiment. The result proves that the method for IR simulation scene has advantages such as： less job in target modeling, higher operation speed, higher analysis accurate.
