摘　　要：云背景对各种红外探测系统的探测识别能力有很大影响。为了更好的研究云背景对红外探测系统的影响,需要建立准确、形象、直观的探测器观察到的云背景红外辐射模型,生成相应的云红外图像。利用分形云插值计算方法和高斯一维随机插值算法,建立云的运动模型和光照模型。利用云层浓度跟高度的关系建立云层模型。实现了对云层形象、直观、准确的仿真。研究结果对红外制导武器在有云飞行对抗过程中的抗干扰评估具有一定参考价值。It has a great impact on detect recognition to kinds of infrared detection system about cloud background.In order to research the cloud background on infrared detection system,it need to establish the accurate,image,intuitive cloud background infrared radiation model which detector observed and generate the corresponding cloud in infrared image.Using fractal cloud inter polaion algorithm and Gaussian 1-D stochastic inter polaion algorithm,cloud motion model and the light model are build.Using the cloud concentration with height relationship build cloud model,it realized the cloud image,intuitive,accurate simulation.The research results have some reference value to infrared guided weapons＇ anti-jamming evaluation in antagonism process with clouds flying.
