摘要
通过分析烟幕遮蔽目标的原理,建立高斯扩散模型、烟幕消光模型和温度衰减模型,对不同状态下烟幕的红外辐射进行实时计算,模拟了烟幕红外图像的动态变化。初步实现了风力,重力等对烟幕的影响效果,提高了烟幕红外图像仿真的逼真度。
The extinction model,dispersion model and temperature attenuation model are established through the analysis of the theory of smoke obscuring the target.A dynamic IR image of smoke is simulated by calculating smoke＇s surface radiation in different states in real time.The effect of wind,gravity and other factors on smoke is initially realized,which will improve the fidelity of smoke＇s IR simulation.
