摘要红外成像仿真的理论研究及其实现，因其具有强烈的需求和应用前景，尤其是在军事上的运用，已成为目前国内外有关研究机构的重要研究课题。
由于户外场景的红外仿真在大气传输过程中受到许多因素影响，导致了其衰减效应的形成。本文重点讨论不同环境、不同辐射传输方式等条件对红外成像的影响，并运用大气传输、红外辐射、图像处理技术等理论，建立与天气、气候等条件的关系，结合相关经验公式，最终得到户外场景在不同环境、不同辐射传输方式等条件下的红外成像大气衰减效应的仿真模型。
本文以大气传输理论为基础,在仅需提供当时大气和红外目标的几个基本参数的情况下,通过本课题编写的计算程序,能得到较为精确的红外辐射的大气透过率，使仿真的红外图像更为真实，为红外应用系统试验提供了红外测试图像来源。64194

Title For Atmospheric Attenuation Effect of Infrared Imaging Simulation
Abstract Theoretical study of infrared imaging simulation and its implementation, with a strong demand and application background, especially in the military use of the current relevant research institutions at home and abroad has become an important research topic.
Since infrared outdoor scenes in atmospheric transport stimulation process influenced by many factors led to the formation of the attenuation effect. Through the use of atmospheric transport theory, infrared radiation theory, image processing and other theories ,this article focused on different climate conditions such as radiation transmission effect of infrared imaging to establish the relationship between climate and other conditions, combined with relevant empirical formula, and ultimately got the outdoor scenes in a different climate conditions such as radiation transmission infrared imaging atmospheric attenuation effects simulation model.
This paper was based on atmospheric transmission theory, in the present atmosphere and offers only a few basic parameters of infrared target case, by writing the computer program, to get more accurate atmospheric transmittance of infrared radiation, so that the simulation of infrared image more real for infrared applications system provided infrared image source.
Keywords Infrared imaging simulation Propagation in the atmosphere Attenuation effect Atmospheric transmissivity
