摘要
为满足红外探测制导对云背景环境干扰适应性的仿真评估验证需求,开展云背景红外仿真建模方法研究。采用粒子系统及实拍图像两种方法对云的几何特性进行建模,分析了两种方法的优缺点,综合考虑大气、太阳、地面背景对云辐射特性的影响,完成辐亮度计算。在此基础上建立了红外探测装置模型,最后渲染得到云背景环境仿真图像。仿真结果表明,通过该方法可以生成特征丰富的云背景红外图像,红外特性真实可靠。
This paper makes a research on infrared cloud background modeling in order to meet the needs of simulation and verification of infrared detection and guidance adaptability to interference of cloud background environment.Particle system and real image are used to model the geometric characteristics of cloud,and the advantages and dis-advantages of the two methods are analyzed.Considering the influence of atmosphere,sun and ground background on cloud radiation characteristics,the radiance calculation is completed.On this basis,the infrared detection device model is established,and finally the cloud background environment simulation image is obtained.The simulation results show that the method can generate cloud background infrared images with rich features,and the infrared characteristic is true and reliable.
