摘　　要：红外成像仿真技术是解决实际应用中对红外图像数据源需求的重要途径。大气传输是红外成像的必经环节,对红外图像质量有着重要影响,大气传输效应模拟能提高成像的真实感。同一场景在不同大气条件下红外成像的模拟能为特定的图像分析提供数据。在大气传输理论的基础上,研究了红外成像大气作用效果的模拟方法,通过飞艇平台获得的红外图像作为数据,利用大气辐射传输模型进行大气修正得到地面辐亮度基准图像,在此基础上进行了不同大气模式、温度和水汽含量下的红外图像仿真实验,并对实验结果进行了评价,取得了较为理想的仿真效果,为大气效应模拟提供了一种有效的方法。Infrared imaging simulation is an important way to provide infrared images of different time and phase in practical.Atmospheric transmission is absolutely necessary in the process of infrared imaging and it has an important effect on the quality of infrared images.Simulation of atmospheric transmission makes the images more reality.Simulation of images of a scene under different atmospheric conditions can provide resource for special image analysis.The simulation method of the effect of atmospheric transmission in infrared imaging was studied based on the theory of atmospheric transmission.The infrared image obtained by airship could be accepted as data source.The radiance of ground could be obtained by atmospheric transmission model.Based on the radiance of ground,simulating experiments were performed in the conditions of different atmospheric models,temperatures and water vapor contents and the results were evaluated.The simulation results are better.The method is effective for the simulation of atmospheric transmission.
