基于战技融合的空中目标红外图像仿真研究

摘要

As the development of the infrared guided missiles from point-source to non-point sources guidance,it is more and more important to study the infrared imaging of air target.Firstly the more precise temperature field of the air target based on Fluent was calculated.Then considering the infrared radiation characteristics of the target,the environ-ment and the sun,the infrared radiation intensities of the air targets were calculated.Finally,based on the typical war situation,the infrared images of air targets were simulated using OpenGL.The simulation results show that the method is effective and has high credibility.%随着红外制导导弹从点源寻的制导到面源寻的制导的发展，研究空中目标的红外成像具有越来越重要的意义。文章首先基于 Fluent 流场计算得到空中目标表面较精确的温度场，然后综合考虑目标、环境、太阳的红外辐射特征，对空中目标的红外辐射强度进行计算，最后运用OpenGL 结合典型交战态势，对空中目标红外图像仿真。从仿真结果看，该方法有效，可信度高。
